  • Access to all CodeGym quests
    CodeGym offers several quests: Java Syntax, Java Core, Java Collections, and Multithreading. It is a well-structured course covering all key aspects of Java. You'll find more than 500 mini-lessons and 1200 practical tasks.
  • IntelliJ IDEA plugin
    We teach students to code in IntelliJ IDEA, one of the most convenient and popular IDEs for Java. To make life easier for you, we wrote a CodeGym plugin for IntelliJ IDEA. It lets you get a task in two clicks, and submit it for verification in one!
  • Task requirements
    What's wrong this time? Where's my mistake? Why doesn't my solution work correctly? Get answers to these questions from status indications for each task requirement. After submitting your solution for verification, you'll see which task requirements you have fulfilled and which you have not.
  • Task recommendations
    Task recommendations are based on an analysis of tens of thousands of errors made by previous CodeGym students. When our system recognizes an error, you'll automatically receive a recommendation from the programmer whose wrote the task. It's almost like working with a personal mentor.
  • Instant task verification
    In ordinary full-time courses, the teacher is inundated with a huge number of student programs. He or she is physically incapable of carefully and quickly checking everything. Students have to wait a long time! CodeGym has no such problem: our validator checks your solution instantly. Click a button, and in a couple of seconds you'll know whether your solution is correct. If you made a mistake, you'll get a list of requirements and recommendations on what exactly needs to be fixed.
  • Mini-projects
    It's difficult for beginners to write large programs, since they don't know how to approach them. That's why we invented mini-projects consisting of 15-20 subtasks. Each subtask has detailed instructions on what to do. This lets you gain experience developing relatively complex applications. For example, you will write simple games, an online chat system, a restaurant automation system, and much more.
  • Bonus tasks
    Tasks for future programming rock stars! They are more difficult than ordinary tasks and require much more time and effort, even if you're cruising through your studies. Bonus tasks are devoted to algorithms, patterns, and other topics that many people find difficult.

  • ReCheck
    You completed the task, submitted it for verification, and received confirmation that your solution is correct. But that's not enough for you — You want to try to solve it in a different way! For programmers with such inquiring minds, we added the ability to check multiple solutions for three days after the first correct solution is submitted.
  • Help with resume writing
    Your job search begins with preparing and distributing your resume. And it's best if it's a good resume... How can you tell the difference? If you're invited to several interviews after sending out your resume, then it is good. If two weeks go by and you haven't received a single invitation to interview, your resume is bad. We'll help you make a good resume.

  • Style check
    As a developer, you’ll need to write code that other programmers can understand. It means that you should follow a style guide, which outlines requirements for writing code. CodeGym has a "code style analyzer" that checks whether your code follows the standards and gives you a list of comments on your code.

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"!

Not surfed much through the website. Currently on Lesson 6 of Java Syntax. Loved the platform till now. Exactly what beginners look for. Everything is explained in the simplest form possible with a fun way. Enjoying to learn from here. A great initiative. Looking forward to learn much more from here. Thanks Team CodeGym

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

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.

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.
