In Eclipse, under Windows -> Preference -> Java -> Code Style, you can define code templates for comments and code, and you can setup a code formatter.

I’m wondering if it is possible in Eclipse to have these setting take affect every time I save a source file. Basically, instead of me highlighting everything and pressing Ctrl+Shift+F, I want Eclipse to be responsible for making sure my code is formatted properly.

Is this possible and how do you set it up?

Note On Using the Auto-Format: It’s probably best to choose ‘Format Edited Lines’ as merging changes becomes very difficult when you reformat a whole file that is in source control already that was not formatted properly. Already did this to a co-worker.

    1. In the Toolbar, navigate to: Window → Preferences
    2. In Preferences, navigate to: Java → Editor → Save Actions
    3. Check the following:
      • Perform the selected actions on save
      • Format source code

    This may or may not be available in previous versions of Eclipse. I know it works in:
