Yesterday, I downloaded a great open source editor/IDE for Java (though it’s good for lots of other things too) called SciTE. It’s small, fast, and ahas a nice set of features including fully-customizable syntax highlighting and HTML export of your code. It also makes great printouts of your code. If you have need of a simple but effective IDE but don’t want to 1) pay money for one or 2) learn Emacs, then this might be for you.
