Learn Java Programming Crash Course (Udemy.com)

This Java For Beginners Course Includes Java Basics And Core Java Skills Training To Make You A Software Developer Fast

Created by: Tim Buchalka

Last updated April 2025

Our take

Based on the ratings of 4,578 students, a sample of their written reviews and the syllabus, as the course stood in April 2025. No course pays to be reviewed.

Tim Buchalka's Java crash course runs about 12.7 hours across 150 lectures and 11 sections. The syllabus shows variables, input and output, primitive types, loops, if and switch, methods, operators and string handling. That is the whole list. Despite the crash course label, it is a slow tour of the basics, not a route to a first Java job. It was last updated in April 2025, and more than 21,000 students are enrolled.

Most of the 4,578 ratings are four or five stars, and the praise is for clear, patient teaching. One reviewer says rewatching an earlier video cleared things up, and several used it as a refresher. The complaints are consistent. Some say classes, objects and arrays never appear. One C# developer missed generics, HashMap, try/catch and lambdas. A few mention a section that was promised but never uploaded. The IntelliJ setup videos are dated, and there are no coding exercises, only quizzes.

Reviewers disagree on pace. One found it fast and demanding, while others found it slow, with plenty of 'more on this later' promises. For an absolute beginner, it is a calm first stage. Expect to follow it with something that covers object-oriented Java. One reviewer was heading to Tim's Masterclass course next, and another thought its sample projects were better. Experienced programmers may find this too thin, as the C# reviewer did.

Best forComplete beginners or rusty coders who want a patient pass through basic Java syntax before moving to a fuller course.
Skip it ifYou expect classes, arrays, collections or lambdas, or you know C# and want Java's real differences.

Pros

  • Patient, clear explanations; one reviewer says rewatching a video cleared things up
  • Starts from installing the tools, with setup videos for Windows, Mac and Linux
  • Short enough at about 12.7 hours to work as a quick Java syntax refresher
  • Most of 4,578 ratings are four or five stars, mainly for the teaching

Cons

  • Never reaches classes, objects or arrays, so it stops well short of job-ready
  • IntelliJ setup videos are dated, and reviewers say a promised section was never added
  • No coding exercises, only eight quizzes, which one reviewer calls general theory
Tim Buchalka is an excellent teacher, very pleasant to listen to and to learn from. The course has given me a good basic understanding of Java, thanks to Tim and the practical exercises.
Robert Aalderink, a student

The Beginner label fits, since it assumes no coding and installs tools first, but it only covers the first rung of Java.

Course Description

If you want to learn to program in Java in far less time than you previously thought possible then read on.

The world today is a hectic place.  Most of us have very little spare time. Once we have worked (or studied), slept, spent some time with friends and family there is little time left to think about a career.

In order to become a software developer you need programming skills.  But how can you get those skills in the minimum amount of time and still have a life along the way?

This course was designed to teach you the essential Java programming skills you need to get your first programming job, or perhaps a promotion to a more senior position.  And to do it in the shortest possible amount of time.

Here is a review written by one of the students in the course.

"Tim is such a great instructor! He just have that magic in him that makes me understand what he is teaching!" - Henrik Ferrari

Do I need to learn 100% of the Java language?

No!  To understand how this course can help you, there is a need to understand how programming languages are constructed.  The creators of these languages try and add every single feature they think someone might need, ever.

A large part of the language rarely gets used, and sometimes not at all.  It's the same with software.  If you have used a spreadsheet in the past, I'd lay odds that you use it for basic spreadsheet work, and you rarely, if ever go into some of the advanced functionality.  The basic functions of the spreadsheet are what most people use.

Imagine if you had to learn every feature of the spreadsheet program?  How long would it take, and would most of that information be useful to you?  Especially if you were learning it to get a job and that job only required basic spreadsheet skills.

Switching back to programming, if your goal is to get your first programming job, then why not only learn what you need to achieve that goal.  And worry about the other stuff when and if you need it.

That's what this course is all about - giving you the skills you need quickly without any fluff or useless information.

The course is aimed at complete beginners.  

We assume you have never programmed before in this course and start from scratch and show you step by step how to download and install the tools, through to writing your first programs, and from there we move to more and more of parts of the Java language that you need to understand.

If you are already a programmer, you will still find value in this course - It's very common for programmers to want to learn a second or third programming language, and doing so makes you more valuable and opens up career opportunities.

As this is a crash course you can get skilled in Java, fast.

Here is what a student said about another of the instructors courses.

"This course is AMAZING!!!!   The teaching is thorough with lots of helpful exercises in various formats! The TA responded very quickly to my question! Thank you!" - Joy Hope

What version of Java will I learn?

All videos in the course have been recorded using the very latest version.  Java 11.  It's recommended that you follow along with that version, but if you have an older version most of the course should work just fine.

Java 11 is the version you will want to learn because Oracle have designated it as the LTS version of Java - meaning they will support it for many years to come.  The reason they do this is so large companies can have a particular version of Java employed on the clients sites for years without worrying about new versions of Java crashing previously working programs.

Java 11 will get updated regularly over this time, but it will remain version 11.   Oracle also have new Java versions coming out six monthly, but as soon as a new version is released, the previous version is no longer supported.

As such you should learn Java 11 which gives you the most useful skills for your future employer.

I heard that you have to pay to use Java 11.

It's true that Oracle charging businesses to use Java 11, but students and professional developers alike never need to pay for Java.  It's 100% free.  And even if that ever became a problem in the future, there is the free OpenJDK version of Java that has no restrictions.

The bottom line is that you do not need to pay anything to legally use Java 11.

What will you learn in the course?

You'll learn the essential Java skills needed to become employable as a Java developer.

  • Creating a Java basic program

  • All about the Java compiler

  • Data Types, Variables, Conditional Processing, Loops, Classes, Operators, Expressions - all the good stuff.

  • Check out the curriculum on this page for a list of what is covered in the course.

In the course you will work with a lot of Java example code.  You will start with Java code that was badly written.  You'll see why it's bad, and then as you progress through the course, you will improve it and make the code bug free.

This approach, along with smaller snippers of code will help you become a programmer as well as think as a programmer.  And as a result you will learn how to get the most out of Java.

What about course updates?

The course will get regular updates - We already have a document in the course that outlines what content is still to be added - We envisage it will be around sixteen hours once done.

It's shorter than that now, but we are adding videos almost every day at the moment.

The instructors have built up a good history of updating their courses in the past on Udemy and that will continue in this course.

What about the instructors?

Your instructors Tim and Goran have a combined 40 years of professional software development experience between them.  They have worked for prestigious  companies such as IBM, Mitsubishi, Fujitsu and Saab. Their professional experience means you are learning from true experts with real commercial programming experience.

Tim has 18 years experience as a Java developer, and Goran whilst a lot younger than Tim is Oracle Java certified.   You will be working with professional software developers who will be teaching you the right way to code based on years of experience.

What's more, there other courses on Udemy have  hundreds of thousands of enrolments and literally tens of thousands of reviews.  They have built up an enviable record of creating best selling and highly rated courses that help people just like you learn to program and move into a programming career.

It's a great course, however, you will need to be familiar with Java somewhat to do well in this course. This course moves fast. I found that in order to enjoy this course one would need to be rather a quick study and catch new and complex material rather fast. You will need a strong mind, time, discipline, patience, and commitment. It's a tough course and you must love Java to do well here. At times, you will have a new complex idea introduced to you and then a new complex idea build upon that; and Java is about it once you become a more advanced programmer.

By Tiffany Morningstar on 2/27/2022

I really liked the way concepts were explained, demonstrated, and summarized for each section. If I ever found myself stuck, all I had to do was re-watch a previous video in the course, and it cleared things up for me. Concepts that I was confused about from a previous course were explained much more clearly here. Might just need an update on the install/setup of IntelliJ, as it has changed. I was able to sort things out, but it was a bit of a distraction in the beginning.

By Sean Perron on 7/23/2021

I like all of Tim's courses and this is no exception. If I had one complaint it was using the pre-made programs as examples. I appreciate the "why" of this, but I did feel a little disconnect from other examples that we'd type in ourselves. 100% subjective and I'm sure for others this worked great. I just found it a little off which made the material in those sections not stick as well. Still, great examples, great explanations. I'm on the the Masterclass one next :)

By Robert Fogg on 1/11/2021

I will rate this course the full 5 stars available because of the course content, the instructor, and the assistance from team members when questions were asked. This is the first actual computer course that I have taken and largely enjoyed. In the 1960s I was first introduced to computer programming. This was presented largely as 1s and 0s put together to print out images using the letter x. Needless to say, not very well presented, for now in my retirement years I am back to try it again. Tim Buchalka has a long career background behind his broad skillset. His accent and mine are clearly from two different worlds! However, through time I have noticed that when an individual may speak a version of "English" that differs from that I am most familiar with, I listen harder or deeper or more intently. Yes concentration may arise from a variety of tools. There were in fact times that I had questions. These questions were responded to within a very reasonable time span. Along the way, to expedite these Q&A opportunities, methods of computer literacy previously not known were described and implemented. I must close by offering a design suggestion to Tim for consideration. Is there a way as you revise and update your various programs, to include and incorporate more hands on exercises and opportunities? The more advanced portion of this course offers a hands on learner the opportunity, even while following along with Tim, to include tactile functionality into a good learning mix. Thank you for this course Tim. Hope many others may also gain insight. -Bob...

I WAS ABLE TO LEARN WHAT I WANT I THINK THIS COURSE IS BEST TO LEARN JAVA ....
THEY MADE JAVA EASY ....

By 213752-Dev Raj on 12/20/2020

excellent course, please keep it up.

By Adithya Santhosh on 12/20/2020

This was the worst course I could ever find after some installation-related stuff, when you actually start programming he starts talking about class, structure, etc. I'm a complete beginner and I literally not understand a thing. And in the second lecture, he gave us a program and tells us to copy and paste the whole thing and gave an explanation of 2 lines, and the lecture ends. Do not get this course it's not for beginners. HE tells us to do another course and return to this one, but there is no link or any name of the course to take as a prequisite.

By Kangkang on 12/13/2020

It didn't take me too much time to cover the essence of the course. I like the chapter "Dealing with Strings", especially.

By Michael Elkin on 11/16/2020

It's good. Personally, I could use a faster pace, but I am not a typical Java newbie. (I have 30 years of mainframe programming experience, and I've learned dozens of languages.)

Pure gold.
