Student here, I just use emacs, although I use Eclipse with Java. The reason is that everything else I have to do in Java is made to be used with Eclipse, so it's a lot less pain using Eclipse.
Off course, they never tell you to use Eclipse, so all of the newbies start of on drJava, which is shit. To the point where they don't even think enough to make the text look nice. It's a text editor, where you look at text all day. Make it look nice, ffs.
