Top 5 Free Java Courses for Beginners to Learn Online in 2021 - Best of Lot

We all love free resources, don't we? If you want to learn Java online in 2021 and looking for the best free core Java online courses then you have come to the right place. Earlier, I have shared the best Java courses for beginners and in this article, I am going to share the best free courses to learn Java online. There was a time when I buy a lot of books when I was preparing for my engineering entrance exam but I only ended up buying books not reading them. After that, I changed my habit to first try to read a book on loan or trying free resources and only buying when I really need them. When I started my programming journey, mostly I learn from free resources like free courses and books and there I developed the passion to collect free resources as well. 

I agree that paid resources are often better than free resources like books and courses but if you are just starting your journey, it's the free resource that you should try first. Once you have some background and interest, you should consider buying a proper book or courses for comprehensive learning.

Thankfully, there is a lot of legal, free resources available on the web, including books, eBooks, online courses, and PDFs. If you are someone who enjoys learning at your own pace by taking online free courses then you have come to the right place.

Today, I am going to share some of the best free Java courses for beginners. When I say beginners, I mean, someone who is starting from scratch, knows nothing about Java but may or may not know a little bit about programming.

Remember, free doesn't mean non-valuable, which many people think, of course, paid resources are often better, but you can still learn Java online from these free resources. You can take these free Java courses to start your journey into the beautiful world of Java programming.

Btw, if you don't mind spending few bucks to learn a valuable skill like Java Programming then I also recommend you to join The Complete Java Masterclass course by Tim Buchalaka on Udemy. This is a massive 80+ hour course that you can get for just $10 on Udemy sales. It's one of the most comprehensive, well-structured, and up-to-date courses to learn Java in depth.

Thanks for this article :) Can you suggest a good online course (paid or otherwise) which project based? I am already going through Tim Buchalka's course on Udemy and have completed about 50% of it (up to Section 12 - Java Collections)so I guess I know the basics of Core Java.

Thanks again and will be looking forward to your suggestions :)
