Some time we need to change the author name of the files we create by eclipse rather than the system user name.
to do so:
1- edit eclipse.ini file in the eclipse directory.
2- add the following line after -vmargs line
-Duser.name=your name
Or we can also change it from here(recommend):
Window -> Preferences -> Java -> Code Style -> Code Templates -> Comments
Edit the Comment: Files and change $(user) to our desired author_name.
