I recently started trying to write java with Xcode but have encountered a problem. A pre-loaded "Hello World" program has been written and does not go away even when I start a new project. I can erase the code and write my own, but when I compile and run it it keeps running the same stupid "Hello World" program. I tried everything - saving my new code, exiting the program, and trying again, and I installed all updates. Has anyone else seen this problem?
