What do you get with a Premium subscription? Premium subscription
  • 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.

One year course at Java University
  • Opportunity to become a Java developer from scratch
    The course consists of five training modules lasting from one and a half to three months. At the end of each module, there are final projects under the guidance of a mentor. The course program includes the basics of Java (materials of four quests of the JavaRush course) + modules on databases, Spring and Spring Boot.
  • Regular homework
    After each online class, students do their homework: they give lectures and solve problems with automatic verification in a separate JavaRush quest, which is available only to students of the annual training program.
  • Private chat support
    Each group on the course has its private Slack chat, in which course mentors and support specialists answer student questions, publish additional tasks for those ahead of the curriculum, publish materials from past video lectures, and all the necessary information about upcoming classes.
  • Group online classes with mentors
    The 12 Month Java Developer course includes online classes with experienced Java mentors. Lectures are held twice a week for two hours. On them, teachers explain to students a new theory, analyze difficult moments from homework, and answer students' questions.
  • Implementation and verification of final projects
    In addition to homework after each lecture, the logical conclusion of each module is the implementation of a practical project under the guidance of a mentor, which will help consolidate the skills. So, well, do something cool!
  • Course Completion Certificate
    We are 100% convinced that students who complete all training modules, complete all homework assignments, and defend all final projects are ready-made juniors. Therefore, upon graduation, we issue a diploma that confirms qualifications and helps create a resume that will allow graduates to find a job.

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"!

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

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.

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.

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.
