Here’s what CodeGym students say about the course
When its come to java, I really regret that why I have not encountered with CodeGym before. CodeGym is based on mantra of education should not be boring with 80% Practical hands on tasks and 20% only required theoretical knowledge, also having in between motivational lectures and videos makes learning fun and easy. If you’re learning java and you encounter code gym then you’re search ends because you’re future in safe hand. All the best!

I have done many java courses. This is by far the best one and it doesn't teach you the concepts just to memorise, you also get a good understanding which is more important imo. Happy coding!

Lots of practical stuff, short lectures, jokes, a plot make CodeGym a top-notch platform to learn Java. I always recommend it to my students as a good place to start programming. This course has an absolutely amazing approach to teaching that keeps your brain engaged and motivated. Keep it up, CodeGym!

Hands down the best site to learn java and I really enjoy the story. It's like reading a comic book and learning programming at the same time.
