Comment width and line wrapping is set in Preferences->Java->Code Style->Formatter, then click on the Edit button and select the Comments tab. I like Line Width for Comments to be 120.

Code line wrapping is set nearby, in Preferences->Java->Code Style- >Formatter, then click on the Edit button and select the Line Wrapping tab. I like a line width of 120 and indent size of 4.
