I know it isn't practical to use Xcode for Java & C++, but I only need it to get by for the school projects (silly, one-file classes). And I would like to avoid having to install different IDEs. My question is, how do I use Xcode without a project? (using it with a single .java or .cpp file) I've tried opening the .java file, but all the build, run, debug, etc options are greyed out. Thank you.
