Good IDE?

["B. John Gilger" <bjgilger earthlink net>]

I'm not interested in starting a holy war.  I would just like your
collective sagacious opinions :)

Has anyone found a good IDE for C/C++ and Java?  I'm realltively new to
the gnome community, but somewhat less new to linux.  I like using emacs
and gcc, but I was wondering if there was an open source (gnome?) app
that integrates things similar to the way it is done with Borland's
Builder, Code Warrior, or (dare I type it?) M$ Visual C++?

If it matters, I'm running RH6.2 with their version of gnome.
