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.
