- Really helped me grasp the basics of Java that I couldn't really understand otherwise. I highly recommended this for new programmers or even lightly experienced ones such as myself and I will 100% recommend this to anyone I know who is into coding.Seamus B.Verified Learner
- Easy to follow and well explained. The concepts cover the range of topics that are vital to getting started in Java and challenging enough to be useful, but with enough help to let you understand if you get stuck.Chris J.Verified Learner
- I loved this course. It was very on pace for somebody who wanted to learn how to program properly. I've bene trying to learn for many years, but no one has explained it so simply as Codecademy. Thanks Codecademy!Mihai C.Verified Learner
