How to copy a GitHub Java project into your own workspace

This brief howto discusses several ways to copy a GitHub Java project into your own workspace so you can edit, compile, and run/test it.

Method 1 (highly discouraged)

This method is highly discouraged because it is tedious and error-prone.

1. Create a new project in your development environment, such as IntelliJ IDEA.
2. For each file in the GitHub project you are copying, create a file in your new project, then copy and paste the contents of the original file to your local file.
