IntelliJ IDEA 2021.3 Help

Learn IDE features

IntelliJ IDEA includes a built-in Features Trainer. This interactive training course on IDE basics can help you learn how to do some common tasks, such as refactoring code, navigating through projects, and more.

The course is divided into several tutorials, each with a number of lessons that teach you how to do a specific task. You can start the course or a specific tutorial from the Welcome screen or from the Learn tool window.

To complete a lesson, you need to finish all the tasks in it. However, there is no need to go through all the lessons and tutorials – you can choose to do only the ones you find most relevant, see Start Learning and Switch between lessons and tutorials.

Before you start

  1. Make sure, you are using IntelliJ IDEA version 2020.3 or later.
