Quickstart Guide

JetBrains Academy

Learn programming by creating working applications with JetBrains Academy, a project-based learning platform.

Learn by doing

Go beyond lectures — learn by developing. Choose a project and work through a curriculum that contains all the concepts necessary to build it. Challenge yourself to integrate everything that you’ve learned into your applications.

See how it's all related

Explore new topics and projects that become available to you as you improve. Navigate the Knowledge Map, which displays your progress, the full scope of available topics, and the connections between them.

Learn from inside your IDE

Master professional tools and become an accomplished developer. Enjoy the platform’s full integration with JetBrains IDEs while working on your projects.

Introduction to Java

Please welcome a series of courses on the main Java concepts: Introduction, Statements and Arrays, Collections, and Classes. They include both the theory and coding practice with inline IDE tips and tricks.

Please note that the courses are currently in Beta. Stay tuned for upcoming improvements and share your feedback in our tracker or twitter.

Apache Beam Katas

Beam Katas is a course that provides a series of structured hands-on lessons to get started with Apache Beam. Solve exercises of gradually increasing complexity and get experience with all the Apache Beam fundamentals such as core transforms, common transforms, and simple use cases (word count), with more katas on the way.

To begin the course, go to Learn ⟶ Browse Courses. Search for Beam Katas, and once the course is loaded into the IDE, you’re good to go.

Integration with Stepik

Stepik is a learning management and MOOC platform, which can be used by an educator to share courses with you privately. Stepik has a lot of public courses available, which you can access from your IDE.

Progress synchronization

If you like learning the theory lessons on Stepik but prefer to do the coding exercises in the IDE – you don't need to worry about losing your course progress. All your progress is synchronized between the platforms.

Importing more courses

You can import any course from Stepik that has programming tasks, which you can solve right inside the IDE. You can easily switch back-and-forth with Stepik any time you want.

Professional Environment

Productivity features such as smart code completion, code inspections, a visual debugger, and more not only boost your learning productivity, but later help you switch easily and seamlessly to other JetBrains tools.

Enjoy a fine–tuned workspace

Feel more at home with your IDE and help yourself stay focused and avoid distraction, with customizable color and keyboard shortcut schemes, and all the look-and-feel settings you need for productive development.

Learn faster with a smart editor

Take advantage of language-specific syntax & error highlighting to help you avoid code mistakes. Learn how to style your code right with the code formatting, and don't ever get stuck thanks to code completion and quick documentation.

Run & debug your code

Run your code to be sure everything goes right. Use the powerful debugger with a graphical UI to find out what went wrong—set breakpoints, run your code step by step and have all the information available to you at your fingertips.
