IntelliJ IDEA

This is a printer-friendly version. It omits exercises, optional topics (i.e., four-star topics), and other extra content such as learning outcomes.

Project Setup :

Running IntelliJ IDEA for the First Time

A slightly more detailed explanation (from CodeLaunch) with some additional info at the end.

Code Navigation :

Some useful navigation shortcuts:

  1. Quickly locate a file by name.
  2. Go to the definition of a method from where it is used.
  3. Go back to the previous location.
  4. View the documentation of a method from where the method is being used, without navigating to the method itself.
  5. Find where a method/field is being used.

Debugging: Basic :

This video (from LaunchCode) gives a pretty good explanation of how to use the IntelliJ IDEA debugger.

Refactoring :

This video explains how to automate the 'Extract variable' refactoring using IntelliJ IDEA. Most other refactorings available work similarly. i.e. select the code to refactor → find the refactoring in the context menu or use the keyboard shortcut.

Here's another video explaining how to do some more useful refactorings in Intellij IDEA.
