How do I use a class from my Jar file in my IntelliJ project?

Question

I have a jar file and I am trying to use classes from that file in other programs, and the only way I know how to do that is by copying and pasting the code, which is less than ideal.

If you do not use Maven or Gradle - add this jar as a Global library to an IDE in File | Project Structure | Global Libraries tab by selecting + then Java option:

if you use Maven or Gradle - install this library into the local Maven repository (see How to add local jar files to a Maven project?) and configure it via Maven/Gradle build configuration.
