So...
Other people on this list have attempted to help prior to this reply. They are
much nicer than
I.
1. You *never* asked a question. You posted a bit of code and indicated
there was an
error. You didn't indicate that you tried to figure out the error or anything
else. The people
who subscribe to this list aren't your parents and are under no obligation to
try to read your
mind (assuming your parents have that obligation) to solve your _unstated_
problems.
2. This mailing list is to discuss Netbeans issues. Basic java problems
really shouldn't be
addressed here, although I might be in the minority in this mailing list with
that opinion.
There are ample places other than this list to find an answer to your implied
problem.
