Concurrency, Multithreading and Parallel Computing in Java review for 2025

In our review of this course, we try to help you answer all of your most important questions about Concurrency, Multithreading and Parallel Computing in Java as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use MAPCIJ as an abbreviation of the course name?

During our Concurrency, Multithreading and Parallel Computing in Java course review, you might sometimes see us refer to it as MAPCIJ for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and MAPCIJ is simpler and easier for reviewing purposes

The full course name is 45 characters long, including blanks, while MAPCIJ is 6 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 39 characters every time we use MAPCIJ.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to MAPCIJ throughout the remainder of this review.

Is the Concurrency, Multithreading and Parallel Computing in Java course for you?

To determine whether Holczer Balazs’s Udemy course is a good fit for you or not, ask yourself the following questions down below.

The more you answer “yes” to each question, the more likely it is that you’ll like this course.

Can you understand what Holczer Balazs’s course is about in 30 seconds or less?

Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that Holczer Balazs chose for the course, “Concurrency, Multithreading and Parallel Computing in Java”, as well as its subtitle: “Multithreading and Concurrent Programming, Parallel Computation and MapReduce in Java”.

This combo of title and subtitle should be enough to communicate the purpose of the training if Holczer Balazs is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what MAPCIJ is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Among other things, it means Holczer Balazs hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.

For similar reasons, it’s important that you’re able to clearly understand what Concurrency, Multithreading and Parallel Computing in Java is all about from the first few lines of the course description.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of Holczer Balazs’s official description of MAPCIJ

Hi!

This course is about the basics of multithreading and concurrent programming with some parallel concepts. In the 21th century this topic is becoming more and more popular with the advent of Big Data and Machine Learning. We will consider the low level concepts such as threads, synchronization and locks. The second chapter will be about concurrent library: of course there are built in classes and interfaces we can use when implementing multithreaded applications. Then we develope little programs as show-cases for multithreading: the dining-philosopher problem or the students in library simulation. Last chapter is about parallel computing.

Thanks for joining my course, let’s get started!

(Read more about this course on the official course page.)

Does MAPCIJ pass the 30 Seconds Test?

You can read a lot more about Concurrency, Multithreading and Parallel Computing in Java on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?

If so, Holczer Balazs has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.

And, if not, maybe you’re better off looking at other IT & Software classes that are more clearly defined and more tailored to your specific interests.

Did Concurrency, Multithreading and Parallel Computing in Java appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with MAPCIJ above, what is your gut reaction to this IT & Software course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?

Did Holczer Balazs do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, Holczer Balazs’s online course is certainly worth considering some more.

But if not, perhaps it’s in your best interest to consider some other IT & Software courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.

Does Holczer Balazs sound like a course instructor you’d like to learn from?

You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the MAPCIJ course is worth taking.

We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, Holczer Balazs’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.

There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.

(FYI, all Udemy instructors, including Holczer Balazs, have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).

Opening lines from Holczer Balazs’s Udemy bio

Hi!

(Learn more about this instructor on the official course page.)

What did you think about Holczer Balazs after reading just the first few lines of the bio above?

After reading just the first few lines about Holczer Balazs, did it make you more or less interested in taking the MAPCIJ course?

And did it make you feel like Holczer Balazs was more or less credible and qualified to teach Concurrency, Multithreading and Parallel Computing in Java?

Finally, overall, did you feel like you’d receive the proper training from the instructor of this IT & Software course?

As always, we encourage you to listen to your gut instinct, which is different for every student.

Are the MAPCIJ lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the Concurrency, Multithreading and Parallel Computing in Java course, is that the instructors are constantly updating them, including adding and renaming lessons.

So it makes no sense whatsoever for us to list out all the modules and lessons in the MAPCIJ course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.

We do, however, have some tips about reviewing Holczer Balazs’s course structure, so that you can get a better sense of whether this program is worth your time or not.

In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, Concurrency, Multithreading and Parallel Computing in Java, as well as the course’s subtitle, Multithreading and Concurrent Programming, Parallel Computation and MapReduce in Java.

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that MAPCIJ is potentially a good, useful course for you, and you can have more confidence in Holczer Balazs’s teaching abilities and lesson planning.

On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.

Have you taken some free lessons from Holczer Balazs that you enjoyed?

Have you already learned something from Holczer Balazs that you valued or enjoyed?

For example, does the Concurrency, Multithreading and Parallel Computing in Java training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)

But if you weren’t able to get any MAPCIJ lessons for free, have you perhaps watched a YouTube video by Holczer Balazs, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of Holczer Balazs’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with Holczer Balazs’s teaching methods, and the more you enjoy them, the more likely it is that Concurrency, Multithreading and Parallel Computing in Java will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from Holczer Balazs before purchasing this course, since it’s one of the best ways to determine whether MAPCIJ will be helpful for you.)

Are “Concurrency, Multithreading and Parallel Computing in Java” reviews generally positive?

On the bottom of the MAPCIJ page, you can read student reviews of the class.

Prior to August 05, 2025, there were 3,438 students enrolled, 1,718 reviews / ratings, and it was overall rated 4.3 out of 5.

Obviously, the more highly other students rate MAPCIJ the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the MAPCIJ reviews to get an overall sense of them. You don’t have to read each one!

Is Holczer Balazs responsive to student questions in the MAPCIJ training?

You can see what other students have to say about this in their MAPCIJ reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send Holczer Balazs a message through this system quite easily, even if you haven’t bought MAPCIJ yet.

For example, you could say, “Hi, and I came across MAPCIJ while looking at IT & Software courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in Concurrency, Multithreading and Parallel Computing in Java on your own, online?

This is a big one, because Concurrency, Multithreading and Parallel Computing in Java is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Concurrency, Multithreading and Parallel Computing in Java.

Yes, you will be able to interact with the students and the teacher, Holczer Balazs, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of MAPCIJ make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Concurrency, Multithreading and Parallel Computing in Java training that looks something like this:

• The purpose of MAPCIJ can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
• Holczer Balazs is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
• Other MAPCIJ students have great things to say about the program

Other benefits include:

• You get to go through MAPCIJ at your own pace
• You join a community of 3,438 other students taking the course
• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that MAPCIJ would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford MAPCIJ?

Can you comfortably afford the cost of Concurrency, Multithreading and Parallel Computing in Java?

This is an important question to answer, because even if you think MAPCIJ sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before August 05, 2025, the price was $12.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on MAPCIJ with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on Concurrency, Multithreading and Parallel Computing in Java?

By far, the easiest way to get the best and biggest discount on this course is to use the Concurrency, Multithreading and Parallel Computing in Java discount code link at the top of this page.

It will instantly give you the best coupon code we could find for Holczer Balazs’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best MAPCIJ course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting MAPCIJ for a better price, but also with any other Holczer Balazs Udemy course that you’d like to get for cheaper.

How can Google help you get a MAPCIJ discount?

To use this method, do a Google search for the MAPCIJ training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy Concurrency, Multithreading and Parallel Computing in Java promo code” or “Concurrency, Multithreading and Parallel Computing in Java udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with Holczer Balazs’s name and see what happens.

For example, you might do a Google search for “Holczer Balazs Udemy coupons” or “Holczer Balazs course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “Concurrency, Multithreading and Parallel Computing in Java coupons” rather than “Holczer Balazs coupons”.

How can a Udemy sale get you MAPCIJ for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get MAPCIJ for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if Holczer Balazs decides not to participate in the site wide sale, then you won’t get a discount on MAPCIJ, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the MAPCIJ course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a MAPCIJ discount from Holczer Balazs?

If you’re really serious about getting “Concurrency, Multithreading and Parallel Computing in Java” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from Holczer Balazs, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get Holczer Balazs’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in Concurrency, Multithreading and Parallel Computing in Java. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join Holczer Balazs’s mailing list, if you can find it, and then you hope that at some time MAPCIJ will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get MAPCIJ for free?

Of course, the best possible price for the MAPCIJ training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that Holczer Balazs has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “Concurrency, Multithreading and Parallel Computing in Java free coupon” or “Concurrency, Multithreading and Parallel Computing in Java 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even Holczer Balazs has offered free coupons for MAPCIJ in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a MAPCIJ free download?

It’s important to understand that there’s a difference between getting full access to the MAPCIJ training for free legally with a free coupon code vs. finding a way to download MAPCIJ illegally.

If you really want to go the download route, you can do a google search for something like “Concurrency, Multithreading and Parallel Computing in Java download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “Concurrency, Multithreading and Parallel Computing in Java free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, Holczer Balazs created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 3,438 students enrolled in the program.

Can you get a refund on Concurrency, Multithreading and Parallel Computing in Java if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the MAPCIJ training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into Holczer Balazs’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on MAPCIJ no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the MAPCIJ training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing Holczer Balazs could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing MAPCIJ and not liking it, since you can always get your money back.

What is OCP’s overall rating of Concurrency, Multithreading and Parallel Computing in Java?

During this MAPCIJ review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.

So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.

Anyway, after taking a look at the MAPCIJ training, the instructor, Holczer Balazs, and reading what other students have said about this program, we give it an overall rating of 4.5 out of 5.

Ultimately, though, what matters most is what you would rate it based on the same criteria.

Data Structures in Java – Part I (+INTERVIEW QUESTIONS) review for 2025

In our review of this course, we try to help you answer all of your most important questions about Data Structures in Java – Part I (+INTERVIEW QUESTIONS) as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use DSIJ-PI(Q as an abbreviation of the course name?

During our Data Structures in Java – Part I (+INTERVIEW QUESTIONS) course review, you might sometimes see us refer to it as DSIJ-PI(Q for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and DSIJ-PI(Q is simpler and easier for reviewing purposes

The full course name is 55 characters long, including blanks, while DSIJ-PI(Q is 9 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 46 characters every time we use DSIJ-PI(Q.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to DSIJ-PI(Q throughout the remainder of this review.

This combo of title and subtitle should be enough to communicate the purpose of the training if Holczer Balazs is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what DSIJ-PI(Q is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of Holczer Balazs’s official description of DSIJ-PI(Q

This course is about data structures and algorithms. We are going to implement the problems in Java. The course takes approximately 14 hours to complete. It is highly recommended to type out these data structures several times on your own in order to get a good grasp of it.

But if you weren’t able to get any DSIJ-PI(Q lessons for free, have you perhaps watched a YouTube video by Holczer Balazs, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of Holczer Balazs’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with Holczer Balazs’s teaching methods, and the more you enjoy them, the more likely it is that Data Structures in Java – Part I (+INTERVIEW QUESTIONS) will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from Holczer Balazs before purchasing this course, since it’s one of the best ways to determine whether DSIJ-PI(Q will be helpful for you.)

Are “Data Structures in Java – Part I (+INTERVIEW QUESTIONS)” reviews generally positive?

On the bottom of the DSIJ-PI(Q page, you can read student reviews of the class.

Prior to August 05, 2025, there were 2,869 students enrolled, 1,384 reviews / ratings, and it was overall rated 4.4 out of 5.

Obviously, the more highly other students rate DSIJ-PI(Q the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the DSIJ-PI(Q reviews to get an overall sense of them. You don’t have to read each one!

Is Holczer Balazs responsive to student questions in the DSIJ-PI(Q training?

You can see what other students have to say about this in their DSIJ-PI(Q reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send Holczer Balazs a message through this system quite easily, even if you haven’t bought DSIJ-PI(Q yet.

For example, you could say, “Hi, and I came across DSIJ-PI(Q while looking at IT & Software courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in Data Structures in Java – Part I (+INTERVIEW QUESTIONS) on your own, online?

This is a big one, because Data Structures in Java – Part I (+INTERVIEW QUESTIONS) is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Data Structures in Java – Part I (+INTERVIEW QUESTIONS).

Yes, you will be able to interact with the students and the teacher, Holczer Balazs, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of DSIJ-PI(Q make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Data Structures in Java – Part I (+INTERVIEW QUESTIONS) training that looks something like this:

• The purpose of DSIJ-PI(Q can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
• Holczer Balazs is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
• Other DSIJ-PI(Q students have great things to say about the program

Other benefits include:

• You get to go through DSIJ-PI(Q at your own pace
• You join a community of 2,869 other students taking the course
• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that DSIJ-PI(Q would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford DSIJ-PI(Q?

Can you comfortably afford the cost of Data Structures in Java – Part I (+INTERVIEW QUESTIONS)?

This is an important question to answer, because even if you think DSIJ-PI(Q sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before August 05, 2025, the price was $12.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on DSIJ-PI(Q with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on Data Structures in Java – Part I (+INTERVIEW QUESTIONS)?

By far, the easiest way to get the best and biggest discount on this course is to use the Data Structures in Java – Part I (+INTERVIEW QUESTIONS) discount code link at the top of this page.

It will instantly give you the best coupon code we could find for Holczer Balazs’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best DSIJ-PI(Q course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting DSIJ-PI(Q for a better price, but also with any other Holczer Balazs Udemy course that you’d like to get for cheaper.

How can Google help you get a DSIJ-PI(Q discount?

To use this method, do a Google search for the DSIJ-PI(Q training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy Data Structures in Java – Part I (+INTERVIEW QUESTIONS) promo code” or “Data Structures in Java – Part I (+INTERVIEW QUESTIONS) udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with Holczer Balazs’s name and see what happens.

For example, you might do a Google search for “Holczer Balazs Udemy coupons” or “Holczer Balazs course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “Data Structures in Java – Part I (+INTERVIEW QUESTIONS) coupons” rather than “Holczer Balazs coupons”.

How can a Udemy sale get you DSIJ-PI(Q for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get DSIJ-PI(Q for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if Holczer Balazs decides not to participate in the site wide sale, then you won’t get a discount on DSIJ-PI(Q, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the DSIJ-PI(Q course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a DSIJ-PI(Q discount from Holczer Balazs?

If you’re really serious about getting “Data Structures in Java – Part I (+INTERVIEW QUESTIONS)” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from Holczer Balazs, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get Holczer Balazs’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in Data Structures in Java – Part I (+INTERVIEW QUESTIONS). Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join Holczer Balazs’s mailing list, if you can find it, and then you hope that at some time DSIJ-PI(Q will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get DSIJ-PI(Q for free?

Of course, the best possible price for the DSIJ-PI(Q training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that Holczer Balazs has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “Data Structures in Java – Part I (+INTERVIEW QUESTIONS) free coupon” or “Data Structures in Java – Part I (+INTERVIEW QUESTIONS) 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even Holczer Balazs has offered free coupons for DSIJ-PI(Q in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a DSIJ-PI(Q free download?

It’s important to understand that there’s a difference between getting full access to the DSIJ-PI(Q training for free legally with a free coupon code vs. finding a way to download DSIJ-PI(Q illegally.

If you really want to go the download route, you can do a google search for something like “Data Structures in Java – Part I (+INTERVIEW QUESTIONS) download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “Data Structures in Java – Part I (+INTERVIEW QUESTIONS) free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, Holczer Balazs created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 2,869 students enrolled in the program.

Can you get a refund on Data Structures in Java – Part I (+INTERVIEW QUESTIONS) if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the DSIJ-PI(Q training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into Holczer Balazs’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on DSIJ-PI(Q no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the DSIJ-PI(Q training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing Holczer Balazs could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing DSIJ-PI(Q and not liking it, since you can always get your money back.

What is OCP’s overall rating of Data Structures in Java – Part I (+INTERVIEW QUESTIONS)?

During this DSIJ-PI(Q review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.

So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.

Anyway, after taking a look at the DSIJ-PI(Q training, the instructor, Holczer Balazs, and reading what other students have said about this program, we give it an overall rating of 4.7 out of 5.

Ultimately, though, what matters most is what you would rate it based on the same criteria.

This is the best Udemy Introduction to SQL and MySQL coupon code discount for 2025.

So if you’re interested in Holczer Balazs’s “Introduction to SQL and MySQL” course, which will help you increase your IT & Software skills, get your discount on this Udemy online course up above while it’s still available. (The coupon code will be instantly applied.)

Introduction to SQL and MySQL review for 2025

In our review of this course, we try to help you answer all of your most important questions about Introduction to SQL and MySQL as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use ITSAM as an abbreviation of the course name?

During our Introduction to SQL and MySQL course review, you might sometimes see us refer to it as ITSAM for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and ITSAM is simpler and easier for reviewing purposes

The full course name is 29 characters long, including blanks, while ITSAM is 5 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 24 characters every time we use ITSAM.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to ITSAM throughout the remainder of this review.

Is the Introduction to SQL and MySQL course for you?

To determine whether Holczer Balazs’s Udemy course is a good fit for you or not, ask yourself the following questions down below.

The more you answer “yes” to each question, the more likely it is that you’ll like this course.

Can you understand what Holczer Balazs’s course is about in 30 seconds or less?

Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that Holczer Balazs chose for the course, “Introduction to SQL and MySQL”, as well as its subtitle: “Learn the basics of the most popular programming language designed for managing data”.

This combo of title and subtitle should be enough to communicate the purpose of the training if Holczer Balazs is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what ITSAM is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Among other things, it means Holczer Balazs hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.

For similar reasons, it’s important that you’re able to clearly understand what Introduction to SQL and MySQL is all about from the first few lines of the course description.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of Holczer Balazs’s official description of ITSAM

Learn the basic concepts and functions that you will need to make queries with the most popular data manipulating programming language, SQL. This course is about SQL commands in the main. You will learn the basics of queries. This is a fundamental part of databases so it is definitly worth learning.

Section 1:

Section 2:

(Read more about this course on the official course page.)

Does ITSAM pass the 30 Seconds Test?

You can read a lot more about Introduction to SQL and MySQL on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?

If so, Holczer Balazs has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.

And, if not, maybe you’re better off looking at other IT & Software classes that are more clearly defined and more tailored to your specific interests.

Did Introduction to SQL and MySQL appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with ITSAM above, what is your gut reaction to this IT & Software course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?

Did Holczer Balazs do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, Holczer Balazs’s online course is certainly worth considering some more.

But if not, perhaps it’s in your best interest to consider some other IT & Software courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.

Does Holczer Balazs sound like a course instructor you’d like to learn from?

You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the ITSAM course is worth taking.

We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, Holczer Balazs’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.

There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.

(FYI, all Udemy instructors, including Holczer Balazs, have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).

Opening lines from Holczer Balazs’s Udemy bio

Hi!

(Learn more about this instructor on the official course page.)

What did you think about Holczer Balazs after reading just the first few lines of the bio above?

After reading just the first few lines about Holczer Balazs, did it make you more or less interested in taking the ITSAM course?

And did it make you feel like Holczer Balazs was more or less credible and qualified to teach Introduction to SQL and MySQL?

Finally, overall, did you feel like you’d receive the proper training from the instructor of this IT & Software course?

As always, we encourage you to listen to your gut instinct, which is different for every student.

Are the ITSAM lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the Introduction to SQL and MySQL course, is that the instructors are constantly updating them, including adding and renaming lessons.

So it makes no sense whatsoever for us to list out all the modules and lessons in the ITSAM course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.

We do, however, have some tips about reviewing Holczer Balazs’s course structure, so that you can get a better sense of whether this program is worth your time or not.

In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, Introduction to SQL and MySQL, as well as the course’s subtitle, Learn the basics of the most popular programming language designed for managing data.

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that ITSAM is potentially a good, useful course for you, and you can have more confidence in Holczer Balazs’s teaching abilities and lesson planning.

On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.

Have you taken some free lessons from Holczer Balazs that you enjoyed?

Have you already learned something from Holczer Balazs that you valued or enjoyed?

For example, does the Introduction to SQL and MySQL training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)

But if you weren’t able to get any ITSAM lessons for free, have you perhaps watched a YouTube video by Holczer Balazs, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of Holczer Balazs’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with Holczer Balazs’s teaching methods, and the more you enjoy them, the more likely it is that Introduction to SQL and MySQL will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from Holczer Balazs before purchasing this course, since it’s one of the best ways to determine whether ITSAM will be helpful for you.)

Are “Introduction to SQL and MySQL” reviews generally positive?

On the bottom of the ITSAM page, you can read student reviews of the class.

Prior to August 05, 2025, there were 1,328 students enrolled, 626 reviews / ratings, and it was overall rated 4.3 out of 5.

Obviously, the more highly other students rate ITSAM the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the ITSAM reviews to get an overall sense of them. You don’t have to read each one!

Is Holczer Balazs responsive to student questions in the ITSAM training?

You can see what other students have to say about this in their ITSAM reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send Holczer Balazs a message through this system quite easily, even if you haven’t bought ITSAM yet.

For example, you could say, “Hi, and I came across ITSAM while looking at IT & Software courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in Introduction to SQL and MySQL on your own, online?

This is a big one, because Introduction to SQL and MySQL is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Introduction to SQL and MySQL.

Yes, you will be able to interact with the students and the teacher, Holczer Balazs, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of ITSAM make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Introduction to SQL and MySQL training that looks something like this:

• The purpose of ITSAM can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
• Holczer Balazs is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions

• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that ITSAM would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford ITSAM?

Can you comfortably afford the cost of Introduction to SQL and MySQL?

This is an important question to answer, because even if you think ITSAM sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

If you’re really serious about getting “Introduction to SQL and MySQL” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from Holczer Balazs, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get Holczer Balazs’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in Introduction to SQL and MySQL. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join Holczer Balazs’s mailing list, if you can find it, and then you hope that at some time ITSAM will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get ITSAM for free?

Of course, the best possible price for the ITSAM training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that Holczer Balazs has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “Introduction to SQL and MySQL free coupon” or “Introduction to SQL and MySQL 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even Holczer Balazs has offered free coupons for ITSAM in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a ITSAM free download?

It’s important to understand that there’s a difference between getting full access to the ITSAM training for free legally with a free coupon code vs. finding a way to download ITSAM illegally.

If you really want to go the download route, you can do a google search for something like “Introduction to SQL and MySQL download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “Introduction to SQL and MySQL free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, Holczer Balazs created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 1,328 students enrolled in the program.

Can you get a refund on Introduction to SQL and MySQL if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the ITSAM training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into Holczer Balazs’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on ITSAM no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the ITSAM training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing Holczer Balazs could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing ITSAM and not liking it, since you can always get your money back.

What is OCP’s overall rating of Introduction to SQL and MySQL?

During this ITSAM review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.

So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.

Anyway, after taking a look at the ITSAM training, the instructor, Holczer Balazs, and reading what other students have said about this program, we give it an overall rating of 4.6 out of 5.

Ultimately, though, what matters most is what you would rate it based on the same criteria.

This is the best Udemy Introduction to Collections & Generics in Java coupon code discount for 2025.

So if you’re interested in Holczer Balazs’s “Introduction to Collections & Generics in Java” course, which will help you increase your IT & Software skills, get your discount on this Udemy online course up above while it’s still available. (The coupon code will be instantly applied.)

Introduction to Collections & Generics in Java review for 2025

In our review of this course, we try to help you answer all of your most important questions about Introduction to Collections & Generics in Java as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use ITC&GIJ as an abbreviation of the course name?

During our Introduction to Collections & Generics in Java course review, you might sometimes see us refer to it as ITC&GIJ for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and ITC&GIJ is simpler and easier for reviewing purposes

The full course name is 46 characters long, including blanks, while ITC&GIJ is 7 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 39 characters every time we use ITC&GIJ.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to ITC&GIJ throughout the remainder of this review.

Is the Introduction to Collections & Generics in Java course for you?

To determine whether Holczer Balazs’s Udemy course is a good fit for you or not, ask yourself the following questions down below.

The more you answer “yes” to each question, the more likely it is that you’ll like this course.

Can you understand what Holczer Balazs’s course is about in 30 seconds or less?

Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that Holczer Balazs chose for the course, “Introduction to Collections & Generics in Java”, as well as its subtitle: “A guide to understand generics, basic collections and reflection in Java!”.

This combo of title and subtitle should be enough to communicate the purpose of the training if Holczer Balazs is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what ITC&GIJ is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Among other things, it means Holczer Balazs hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.

For similar reasons, it’s important that you’re able to clearly understand what Introduction to Collections & Generics in Java is all about from the first few lines of the course description.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of Holczer Balazs’s official description of ITC&GIJ

Learn the basic concepts and functions that you will need to build fully functional programs with the popular programming language, Java.

This course is about generics in the main. You will lern the basics of generic types, generic methods, type parameters and the theoretical background concerning these topics. This is a fundamental part of Java so it is definitly worth learning.

(Read more about this course on the official course page.)

Does ITC&GIJ pass the 30 Seconds Test?

You can read a lot more about Introduction to Collections & Generics in Java on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?

If so, Holczer Balazs has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.

And, if not, maybe you’re better off looking at other IT & Software classes that are more clearly defined and more tailored to your specific interests.

Did Introduction to Collections & Generics in Java appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with ITC&GIJ above, what is your gut reaction to this IT & Software course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?

Did Holczer Balazs do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, Holczer Balazs’s online course is certainly worth considering some more.

But if not, perhaps it’s in your best interest to consider some other IT & Software courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.

Does Holczer Balazs sound like a course instructor you’d like to learn from?

You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the ITC&GIJ course is worth taking.

We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, Holczer Balazs’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.

There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.

(FYI, all Udemy instructors, including Holczer Balazs, have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).

Opening lines from Holczer Balazs’s Udemy bio

Hi!

(Learn more about this instructor on the official course page.)

What did you think about Holczer Balazs after reading just the first few lines of the bio above?

After reading just the first few lines about Holczer Balazs, did it make you more or less interested in taking the ITC&GIJ course?

And did it make you feel like Holczer Balazs was more or less credible and qualified to teach Introduction to Collections & Generics in Java?

Finally, overall, did you feel like you’d receive the proper training from the instructor of this IT & Software course?

As always, we encourage you to listen to your gut instinct, which is different for every student.

Are the ITC&GIJ lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the Introduction to Collections & Generics in Java course, is that the instructors are constantly updating them, including adding and renaming lessons.

So it makes no sense whatsoever for us to list out all the modules and lessons in the ITC&GIJ course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.

We do, however, have some tips about reviewing Holczer Balazs’s course structure, so that you can get a better sense of whether this program is worth your time or not.

In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, Introduction to Collections & Generics in Java, as well as the course’s subtitle, A guide to understand generics, basic collections and reflection in Java!.

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that ITC&GIJ is potentially a good, useful course for you, and you can have more confidence in Holczer Balazs’s teaching abilities and lesson planning.

On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.

Have you taken some free lessons from Holczer Balazs that you enjoyed?

Have you already learned something from Holczer Balazs that you valued or enjoyed?

For example, does the Introduction to Collections & Generics in Java training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)

But if you weren’t able to get any ITC&GIJ lessons for free, have you perhaps watched a YouTube video by Holczer Balazs, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of Holczer Balazs’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with Holczer Balazs’s teaching methods, and the more you enjoy them, the more likely it is that Introduction to Collections & Generics in Java will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from Holczer Balazs before purchasing this course, since it’s one of the best ways to determine whether ITC&GIJ will be helpful for you.)

Are “Introduction to Collections & Generics in Java” reviews generally positive?

On the bottom of the ITC&GIJ page, you can read student reviews of the class.

Prior to August 05, 2025, there were 3,233 students enrolled, 1,507 reviews / ratings, and it was overall rated 4.3 out of 5.

Obviously, the more highly other students rate ITC&GIJ the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the ITC&GIJ reviews to get an overall sense of them. You don’t have to read each one!

Is Holczer Balazs responsive to student questions in the ITC&GIJ training?

You can see what other students have to say about this in their ITC&GIJ reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send Holczer Balazs a message through this system quite easily, even if you haven’t bought ITC&GIJ yet.

For example, you could say, “Hi, and I came across ITC&GIJ while looking at IT & Software courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in Introduction to Collections & Generics in Java on your own, online?

This is a big one, because Introduction to Collections & Generics in Java is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Introduction to Collections & Generics in Java.

Yes, you will be able to interact with the students and the teacher, Holczer Balazs, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of ITC&GIJ make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Introduction to Collections & Generics in Java training that looks something like this:

• The purpose of ITC&GIJ can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
• Holczer Balazs is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
• Other ITC&GIJ students have great things to say about the program

Other benefits include:

• You get to go through ITC&GIJ at your own pace
• You join a community of 3,233 other students taking the course
• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that ITC&GIJ would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford ITC&GIJ?

Can you comfortably afford the cost of Introduction to Collections & Generics in Java?

This is an important question to answer, because even if you think ITC&GIJ sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before August 05, 2025, the price was $12.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on ITC&GIJ with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on Introduction to Collections & Generics in Java?

By far, the easiest way to get the best and biggest discount on this course is to use the Introduction to Collections & Generics in Java discount code link at the top of this page.

It will instantly give you the best coupon code we could find for Holczer Balazs’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best ITC&GIJ course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting ITC&GIJ for a better price, but also with any other Holczer Balazs Udemy course that you’d like to get for cheaper.

How can Google help you get a ITC&GIJ discount?

To use this method, do a Google search for the ITC&GIJ training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy Introduction to Collections & Generics in Java promo code” or “Introduction to Collections & Generics in Java udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with Holczer Balazs’s name and see what happens.

For example, you might do a Google search for “Holczer Balazs Udemy coupons” or “Holczer Balazs course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “Introduction to Collections & Generics in Java coupons” rather than “Holczer Balazs coupons”.

How can a Udemy sale get you ITC&GIJ for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get ITC&GIJ for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if Holczer Balazs decides not to participate in the site wide sale, then you won’t get a discount on ITC&GIJ, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the ITC&GIJ course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a ITC&GIJ discount from Holczer Balazs?

If you’re really serious about getting “Introduction to Collections & Generics in Java” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from Holczer Balazs, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get Holczer Balazs’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in Introduction to Collections & Generics in Java. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join Holczer Balazs’s mailing list, if you can find it, and then you hope that at some time ITC&GIJ will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get ITC&GIJ for free?

Of course, the best possible price for the ITC&GIJ training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that Holczer Balazs has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

So even Holczer Balazs has offered free coupons for ITC&GIJ in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a ITC&GIJ free download?

It’s important to understand that there’s a difference between getting full access to the ITC&GIJ training for free legally with a free coupon code vs. finding a way to download ITC&GIJ illegally.

If you really want to go the download route, you can do a google search for something like “Introduction to Collections & Generics in Java download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “Introduction to Collections & Generics in Java free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.
