Web Premium Subscription
For Self-Paced Learning on the Interactive Web Development Course
  • Access to the Basic Web Development Course
    The interactive self-paced web development course comprises 48 levels, covering all the basics and several critical topics in web development. The course includes mini-lectures and many practical tasks, making it suitable for beginners and more experienced programmers.
  • WebStorm / IntelliJ IDEA Plugin
    We teach students to work with professional tools for development. We created the CodeGym plugin for WebStorm and IntelliJ IDEA to make it more comfortable for you. With the plugin, you can get a task in two clicks and submit it for verification in one!
  • Task Requirements
    What’s wrong? Where is the error in the solution, and why does the program work incorrectly? You’ll find the answer to this question in the requirement statuses. After submitting the solution for verification, you’ll see which requirements for the task have been met and which have not.
  • Task Recommendations
    When you submit a task for verification, many tests run to find known standard errors. If such errors are found, you receive a recommendation from the task’s developer on how to fix the error best.
  • Instant Task Verification
    The best way to master new material is to practice it. But how do you know if your program works correctly? Someone has to check your tasks! On CodeGym, your code is checked instantly and automatically. You just need to click once, and if your program (solution) is correct, you’ll know it immediately.
  • Task Assistance
    In the "Help" section, you can post your non-working solution and ask for help or advice. You can also help others find errors in their programs. You can access "Help" directly from the task, and within the section, it’s easy to find discussions for the needed task by its ID or name.
  • Continuous Learning
    We save your learning progress. If you need to take a break from solving a large task, that’s okay: you can finish the code when it’s convenient. Just submit the code for verification, and we will save it on our servers. You can return to the task from any device by logging into CodeGym with your account.

I have visited numerous websites and applications that claim to teach Java in the best way possible. But Code Gym stands out of all those websites; because it does what it claims to do. The simplest to the most complex of topics of Java are explained in layman terms so that anyone irrespective of their educational background can learn, practice, and master Java. A major thumbs up to you, Code Gym!

Just this morning I posted in another part that I would not be able to pay for the course. I've been around for 12 levels and I've definitely loved it. There is a saying that I've tried to stick to ever since I saw it: "empty your pockets to fill your mind, for once there will come a time where your mind will fill your pockets" I've got the money from a very close person and plan to take full advantage of the course. Happy coding, everyone!

I'm reluctantly transitioning from manual testing to test automation. I've started a lot of java courses online and this is the first time I feel like I might actually be "getting it"!

Absolutely love this website and its tutorial! I used to have a C class in university, but the professor is too dull and boring to pay attention to, I just skipped the whole course. But I passed the exam cuz I practice a lot, so I know that in programming, practice matter. And when I want to learn Java and found here...jeez, 80% practice, that's what makes you success, couldn't agree more.

12000? Actually, the real figure is 1200 exercises. Which is still challenging in one month.

Thank you for this course, thank you for the work you have done. Since the theory, enshrined in a large practice, is a big plus of this course. Good luck to all. P.S. We are waiting for additions to the course

I never thought coding was possible for me, but, so far, this program has been easy to understand and use. My only request would be to be able to see the best possible solution after getting a solution right, given that there are multiple ways to solve each task.

Something new... The story based approach is what i like the most and at each step there are exercises after a brief lesson which makes it more intriguing. Thanks a lot for such a step.
