I Tested 20+ Java Courses on Udemy - Here are My Top 5 Recommendations

My favorite Udemy Courses to learn Java in depth

credit — Java Course for Complete Beginners with Practical Examples (udemy)

Hello guys, when it comes to learning Java, there is no better place than Udemy. Why? Because Java is very vast and you need to join multiple courses to learn multiple technologies required to become a proficient Java developer, like core Java, multithreading, design patterns, Spring Framework, hibernate etc and Udemy has courses on everything.

Whether you want to learn Java from scratch or you just want to take your Java skills and need courses, then you have come to the right place.

In this article, I am going to share the 5 best Udemy courses you can join to learn Core Java in depth.

I have carefully selected these courses based on my knowledge and experience, and the course quality, considering things a beginner looks into the course like once did.

When I started learning Java, I started with just typing whatever code was given in books like Head First Java or Java: The Complete Reference. I didn’t understand a single line, and whenever I miss command, I got scared to see all those errors, but typing slowly taught me what Java really is.

I learned Java the hard way, but you don’t need to if you join a course where an Instructor is knowledgeable and patient enough to explain what each of those lines means and what happens if you make mistakes.

I am also inclined to bootcamp-style courses where you learn by doing things like solving coding problems or kata in Java or building small projects. Those are the things that will actually teach you programming and software development along with Java.

Remember, Java is just a tool to create software, and the real skill is programming and development, but if you have a good tool like Java, its a lot easier to acquire those skills.

Now, let’s jump into these courses, but if you can’t wait to start with just start with The Complete Java Masterclass course by Tim Buchalaka, this is one of the most comprehensive Java courses on Udemy with more than 80 hours of content and it touches almost all important core Java topics.

2. 60 Days of Java: The Complete Java Masterclass

This is a new course on Java on Udemy, which I recently saw while browsing Udemy. I like the course because it teaches you Java by building real-world projects, which not all courses do.

In this course, you will not just learn core Java but also learn JavaFX, Spring Boot, REST APIs, etc. The course will not just teach you Java A to Z but also teach you how to build real-world projects, including a fully functional To-Do App and REST APIs.

The course is created by Denis Panjuta, a popular Udemy instructor with 400K students and growing, and who is an expert in teaching how to code.

3. The Complete Java Masterclass [Udemy]

This is probably the most popular Java course on Udemy, with over 207,000 students enrolled in this course.

It has got more than 40K 4.6 ratings which speaks a lot about its quality, but the most important thing I like about this course is that the instructor has frequently updated it to include changes from various Java versions.

It’s a comprehensive course with over 72 hours of material, and you will learn all major things a Java developer should know, like data structure, OOP, Core Java Fundamentals, Java Collections, Multithreading, File IO, Networking, Database, Java 8, Unit Testing, and Java 9 to Java 17 changes.

The instructor Tim Buchalka is also a famous Java instructor on Udemy, and that shows enormous social proof associated with this course. Every single concept is explained in detail, and you will learn the concept one program at a time.

You will not only learn concepts but also essential Java tools like Eclipse, Maven, etc, which are essential for Java development.

In short, one of the most complete courses to learn Java and is suitable for beginners as well as Java developers who are starting Java.

4. Java Programming for Complete Beginners — — Java 17 [Udemy]

This is another great course to learn Java on Udemy, and that’s why it’s also the most up-to-date. It uses tools like JShell, which is introduced in Java 9, to teach you how to program in Java.

No doubt, it’s a great tool and really makes trying stuff in Java pretty easy.

The course structure is also very good and follows a step-by-step teaching method. I like the instructor’s approach and teaching style, having gone through some of his Spring courses in the past.

The course is also very comprehensive and covers all important Java concepts like Java basics, Object-Oriented Programming, Java Collections, Generics, Multithreading and Concurrency, Functional Programming, Networking, File handling, and Exception handling.

Once you have gone through a course you will be very comfortable reading and writing Java programs and should also feel confident to take any Java interview if you are learning Java to get a job.

In short, an excellent and most up-to-date Java course as of now, and the best thing is it’s free at the time of writing.

In Udemy, the instructor keeps their course for free for some time to achieve their promotional target, after that, it’s converted into a paid course. So, join it now before it becomes a paid course.

Once you are enrolled in the course, you will have free lifetime access to all its chapters and associated materials.

If you are looking for a Java course that can teach you step by step the meaning of every single line of code, like what a class does, what the main method, what a method, what a member variable, how to run Java program etc then this course is for.

This 61. 5 hour long and comprehensive Java course is created by Abdul Bari, a programmer and teacher with 20 years of experience in the computer science and information technology fields.

Apart from these top 5 Java courses, if you need more, I also recommend you to check out these new courses:

1. Java Programming: A Comprehensive Bootcamp from Zero to Hero by Madan Reddy

2. Java from Zero to First Job, Practical Guide, 2000+ examples by Andrii Piatakha

3. Java Course for Complete Beginners with Practical Examples by Sandor Szekeres

All of these courses also come with coding exercises, which is a new feature of the Udemy learning platform and allows you to code online in a browser and execute your program right from there.

That’s all about the best Udemy courses to learn Java programming from scratch in 2026. I have carefully chosen Udemy courses that not just cover Java well, comprehensively, up-to-date, but also hands-on, and encourage learning by doing.

Also, you don’t need to join all of these courses, you can start with one course where you connect withthe instructor and then only jump on the other course.

I generally learn better by learning from multiple instructor but it totally depends on what suits you better, one instructor or multiple instructors.

One good way is to watch a preview, which I always do before joining any course. If I can watch preview videos without getting bored, then it’s a good sign that I am connecting with the course and instructor; you can do the same.

Also, when it comes to joining courses on Udemy, you can either join them individually, which will give you lifetime access or you can get the Udemy Personal Plan which gives you access to more than 10K Udemy courses for $30 per month.

If you are a lazy learner like me, then I suggest just buying it because then you can learn anytime but if you are motivated and have time, go for Udemy's personal plan, it’s more worth the money.
