The Internet is full of useful resources. No matter what you want to learn there is something useful available for free. You just need to commit your time and effort. At the same time, it's difficult to choose in the huge sea of free tutorials and courses on the internet.
If you are not careful, you will spend most of your time browsing and changing courses without learning anything. That's where a curated list helps. Curation is my hobby and passion. I love to read books and courses which allows me to curate useful resources and share with you guys.
Today I'll share 10 Java Programming Courses which beginners can use to learn Java for free.
Even though the focus is on beginner Java courses --- because beginners are the ones who need the most guidance and help --- I have tried to also include free courses which can be really useful for intermediate and experienced Java developers.
These are some of the really important skill, tools, and technology for experienced Java developers. If you are not familiar with them, it's probably the right time to pick them up to boost your career and skills.
This is the most popular free Java course on Udemy. It probably has the first mover advantage, but the quality of the course is quite good.
If you are a beginner at programming or know a programming language but also want to learn Java, then you can enroll in this course. It's FREE and I guess it always remains free on Udemy.

This is an intermediate Java course. If you have some experience in software development or a background in computer science, then you can take this free course to learn object-oriented programming.
After completing this course, you should be able to develop an object-oriented application in Java, leverage the power of existing libraries, how to build graphical user interfaces, and how to use some core algorithms for searching and sorting data.
And, the best part is that it is project-based, so you'll get some much needed hands-on practice and coding.

Multithreading is an essential part of Java programming and probably the single most important feature which separates a good Java developer from an average Java developer.
There is a high demand for Java developers who can write robust and concurrent code. They also get paid very high salaries.
If you truly want to excel in the Java world, multi-threading and concurrency is the one area you need to conquer, then this course will help you to do that at free of the cost.

Btw, if you have a budget to spend some money on something worth learning, then Applying Concurrency and Multi-threading to Common Java Patterns By José Paumard on Pluralsight is also very good, but, of course, it's not FREE.
You'll need a Pluralsight membership to access the course, which costs around $29 per month/$299 per year but also gives access to their 5000+ online course library.
There is no better way to learn a new programming language than building projects. This is what I call active learning. You cannot learn by simply reading books or watching online courses until you start writing code and creating projects. This makes your mind work actively.
You get familiar with real-world requirements and then you find answers based upon whatever you have learned. In short, use this course for more involved and project-based learning.

A highly recommended free course for anyone learning Java.
Btw, if you feel that theory is bit light on this course then you can also combine this with The Complete Java Masterclass, one of the best and most up-to-date course to learn Java, but not free.
JDBC is an integral part of Java API because most of the real world application you will create in Java will have to work with a database.
Good knowledge of JDBC is required even if you are using advanced frameworks like Hibernate, JPA, or IBatis and this course will provide you with that. It uses MySQL as an example database as it's also free and teaches you how to work with a database in Java using JDBC.

Overall, a perfect course for both beginners and intermediate Java developers looking to brush up their JDBC skill.
This is another beginner level course for Java developers. If you are a computer science graduate or programmer coming from C, C++, or Python background, then you can use this course to quickly get up to speed with Java programming.
It's a short course, not very comprehensive but provides a nice overview from a beginner's perspective.

There is no doubt that IntelliJIDEA is quickly winning the war against Eclipse to replace it as the most popular Java IDEs, but it still a very good IDE to start with. It's FREE and you don't need to pay a license fee, which is required for the full edition of IntelliJIDEA.
As a Java developer, a good knowledge of your IDE is a must, and this course will teach you how to work with Eclipse efficiently. Highly recommended for any programmer starting with Java development.

That's all about some of the free Java Programming courses for beginners. If you want to learn Java, then these courses are more than enough to make you a Java expert. As I have said, these courses cover the vast landscape of Java programming from core Java to advanced Java, from multithreading to JDBC, and from Eclipse to Docker. Hence, it's equally useful for beginners and intermediate Java programmers. Even experts can learn a few things from some of these courses.
Thanks for reading this article. You might be thinking that there is so much to learn, so many courses to join, but you don't need to worry.
I am a particular fan of Udemy courses, not because that I'll get paid if you buy a paid course mentiond in this article but becasue they are very affordable and provides a lot of values in a very small amount, but, ofcourse you are free to choose the course you want.
At the end of the day, you should have enough knowledge and experience about the things mentioned here.
Good luck with your Java journey! It's certainly not going to be easy, but by following these courses, you are one step closer to becoming the Java Programmer, you always wanted to be
If you know any other free Java course which is not in the list but good for beginners, feel free to comment here. All the best with learning.
