10 Best Java Courses and Certifications for Beginners in 2025
A curated list of best online courses & Certifications to learn Java Programming in 2025 from Udemy, Pluralsight, Coursera, edX, etc
If you are a computer science graduate or a programmer 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 best Spring Framework Courses and best websites to learn Java and in this article, I am going to share some of the best Java courses beginners can join to learn Java.
One of the main problems with learning Java is keeping pace with the increasing number of releases. For example, Java 8 was released in 2014 which completely changed how Java is written and now within the last 6 months, we have two major Java releases in the form of Java 14 and Java 15. 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that is up-to-date, otherwise, you will be left behind in the job market and your day-to-day programming job with outdated skills.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, 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 Java Programming Courses & Certifications for Beginners to Learn 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.
Btw, I also review courses and get paid if one of you buys the course from the link in this article.
Without any further ado, here are them:
1. 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 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.
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 changes.
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 the concept one program at a time.

13. CodeGym (learn Java by building Games)
If you like to learn Java by building games and doing interactive programming exercises then you will love Codegym. I recently found this website when one of my reader pointed it and I was amazed with the learning material.
The best thing about CodeGym is that they give you a lot of practice and they also follow 80/20 rule where you will be reading or learning 20% of your time and 80% of time practicing what you learned.
This method works because in real life you will be using top 20% of your skill 80% of time, this true with Java as well, while Java API is very vast with hundreds of classes and third-party libraries, you will be using only 20% of Java most of the time like core Java, Collections and Multithreading.
In other words, CodeGym is like an online course but with 1200 tasks and many games which clearly makes it as one of the best places to learn Java coding.
You can learn more about it here — CodeGym
They have both free and paid options while their free option is good enough to learn Java online, if you can afford, you should definitely try Codegym premium, their paid version, they are also offering 50% discount now.
And, if you want to learn more about it, you can also see my review of CodeGym platform for learning Java.
That’s all about some of the best courses to learn Java in 2025. There are a lot of opportunities for Java developers and once you know Java you will be in high demand.
You can join investment banks which does a lot of Java development, or you can become a mobile application developer by writing games and apps for the Android platform.
You just chose your domain, there will be no shortage of opportunities to give Java’s popularity and penetration into the software development world.
