Top 10 Java Programming Courses for Beginners to Learn Online in 2025 - Best of Lot

If you are a computer science graduate or someone who wants to learn Java and looking for some awesome resources like books, tutorials, and online courses then you have come to the right place. In the past, I have shared some great books, websites, and tutorials to learn Java and in this article, I am going to share some of the best Java courses beginners can join to learn Java in 2025. One of the main problems with learning Java is keeping pace with the increasing number of releases. For example, Java 8 release completely changed how Java is written and after that, we have many Java releases in the form of Java 9, Java 10, Java 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, and now Java 23. But the good thing is that the core of Java is still the same and all its releases are backward compatible.

If you are learning Java first time, then it's very important to choose an online course that is up-to-date, otherwise, you will be left behind in the job market and your day-to-day programming job with outdated skills.

But, before that, let me first congratulate you on making an excellent decision of learning Java in 2025, one of the most popular mainstream programming languages in the world.

The Java Programming language is been around for more than 20+ years now and it has expanded its reach to almost every single field, from small mobile apps to large banking applications running on major Investment banks.

Java is mainly used as a server-side language to create high-performance, low latency servers to handle complex tasks. Java is really big on Investment banks which uses it to write end-to-end trading applications like front-office applications for trade capture, middle office applications to handle booking and allocation, and back-office applications for sending confirmations.

Another area where Java really shines is for creating Android applications. Though Google has now declared Kotlin as the official language for Android app development, Java is still quite big and there is no sign of any slowdown in the coming years.

10 Best Online Courses to Learn Java for Beginners in 2025

In this article, I have chosen some of the best Java courses from Udemy and Pluralsight, which are both comprehensive and up-to-date but at the same time suitable for beginners.

Without any further ado, here are some of the best courses to learn Java Programming from scratch for beginners:

1. Java 17 Masterclass: Start Coding in 2025

This is probably the most popular core Java course on Udemy with over 800K students enrolled in this course.

It has got more than 295K, 4.6 ratings which speak a lot about its quality but the most important thing I like about this course is that instructor has frequently updated it to include changes from Java 8 and Java 9 and recently updated for Java 17, the latest JDK release 

It's a comprehensive course with over 130 hours of material, 50 online coding exercises, and you will learn all major things a Java developer should know e.g. data structure, OOP, Core Java Fundamentals, Java Collections, Multithreading, File IO, Networking, Database, Java 8, Unit Testing and new Java features.

The instructor Tim Buchalka is also a famous Java instructor in Udemy and that shows enormous social proof associated with this course. Every single concept is explained in detail and you will learn concepts one program at a time. It also comes with a certification of completion. 

You will not only learn concepts but also tools that are free like Eclipse, Maven, Git, etc, and essential for Java development.  In short, one of the most complete courses to learn Java and suitable for beginners as well as Java developers who are starting Java after a long time like last seen Java code before JDK 1.5.

This foundation in OOP sets a strong base for learners to develop their programming skills.

The bootcamp also covers Lambda Expressions and Functional Programming, introducing learners to the power of lambda expressions and Java's Stream API. By leveraging these techniques, students can write clean, concise, and efficient code. This addition enhances the versatility and efficiency of their programming abilities.

One of the most appealing aspects of this course is the hands-on learning experience it provides. With over 80 exercises and 18 quizzes, learners have ample opportunities to practice their newly acquired skills and reinforce their understanding. This practical approach ensures that students gain practical experience, enhancing their ability to apply their knowledge in real-world scenarios.

3. Java Programming and Software Engineering Fundamentals Coursera

This is one of the best Coursera courses to learn Java for beginners online and it's offered by Duke University on Coursera. 

Though Java has changed a lot from Java SE 8, it doesn't change much in Java 9 and Java 10, hence the course which covers Java 8 syntax is good and this is one of such courses.

The course is structured really well with a focus on teaching you basic software engineering skills like Data structure and software design and like the previous two courses, this also covers all essential Java topics like Variables, methods, control statements, loops, arrays, List, and Strings, object-oriented programming, file handling, database, multithreading, collections, etc.

It also has a project at the end of specialization where you will build a  Recommendation system in Java, similar to what Netflix has for movie recommendations or Amazon's book recommendations. This would be a simplified version but you will learn a lot by doing that. 

In short, a good course to start with Java programming from scratch. Though, if you want to become a full-stack Java developer, I also suggest you take a look at these full-stack Java courses, which comprise many courses to become a full-stack Java developer in 2025

  

4. Java Programming for Complete Beginners in 250 Steps [Udemy]

This is a relatively new course to learn Java in 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 the 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 would be very comfortable reading and writing the 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 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.

Like a previous Java course, this is also a very detailed and comprehensive course and covers the majority of Java topics a beginner wants to learn like variables, methods, classes, collections, data structures, threads, networking, etc.

On the downside of the course, it's mainly a slide-based course with some code examples here and there. A few more code examples, preferably with new tools like JShell will really help.
