The purpose of this forum is to answer questions on the set-up and use
of the Eclipse IDE. It's not to answer beginning programming or even
general programming questions.

I would suggest a) that you step through in the debugger, b) figure out
how better to state your question and c) try a forum such as
javaranch.com or stackoverflow.com.

Best of luck.
