Intellij - Displaying line numbers

When I first fired up IntelliJ and started using it to edit a Java file, one of the first things I wanted to do was to be able to see line numbers within the file.

Configuring IntelliJ to show line numbers is a no-brainer. Here's how to do it:

  • Select Tools | IDE Options
  • Select Editor
  • In the Display group, click Show line numbers
  • When you're finished here, click OK

That's it. Do this and you're ready to go.

I am using version 9 and the menu structure has changed. The show line number option is now under IDE Settings | Editor | Appearance.
