Hello folks, If you are a computer science graduate or a programmer who wants to learn Java, or someone who wants to start programming with Java, and looking for some awesome resources like books, tutorials, and online courses then you have come to the right place.

Being a Java developer for last 18 years, and author of one of the popular Java blog, Javarevisited (yes, I have been writing Java article since 2010), I often receive requests for recommendation and learning resources.

In the past, I have shared a complete Java Developer RoadMap along with the best books and tutorials to learn Java and in this article, I am going to share some of the best Java courses beginners to learn Java and Programming online.

One of the main problems with learning Java is to keep pace with the increasing number of releases. For example, Java 8 was released in 2014 which completely changed how Java is written and after that we have a new Java version in every six month.

Before you can start with Java 9 and Java 10, you realize Java 17 is coming. 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 the online course which is up-to-date, otherwise, you will be left behind in the job market and your day-to-day programming job with outdated skills.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 main-stream programming language of 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 application running on major Investment banks.

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

My Favorite Courses to Learn Java Programming for Beginners [Free and Paid]

In this article, I have curated some of the best Java online courses from popular online learning websites like Couresra, Udemy and Pluarlsight, 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 buy 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 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 recent Java changes.

The instructor Tim Buchalka is also a famous Java instructor in Udemy and that shows with 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 tools which are free like Eclipse, Maven, etc and essential for Java development.

In short, one of the most complete course 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.

4. Java Programming for Complete Beginners

This is a relatively [new course] to learn Java in Udemy and that's why it's also 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 cover 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 Java program 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 the 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.
