Answer : eclipse short cut keys

In case - http://eclipse-tools.sourceforge.net/Keyboard_shortcuts_(3.0).pdf

What you can also do is - Preferences -> Java -> Code Templates -> Comments -> Files. Add the code. Add a comment that you would like to add to each file.

Then press ctrl+shift+F, this will add the comment placed there to the files.
