EclipseSW has built-in shortcut keys for commenting out and uncommenting your JavaSW code. I use this all the time during development when I want to turn off a section of code or a method call. Eclipse has the ability to do line comments and block comments.

I'll demonstrate this with the Test class shown here.

Test class in Java Editor

First we'll look at adding line comments to a section of code. I start by highlighting the lines of code that I wish to comment out.

Selecting text

Hitting Control-/ comments out the section of code using line comments.

Commenting selection

Hitting Control-/ again uncomments the section of code.
