Exception handling

OK, it runs at least. I put in proper input and it works great. If I put in a zero, it catches it as my negative number statement. If I put in a w, it also catches it as my negative number statement. I'm sure I'm doing something wrong, can anyone else see it? Thanks in advance!

Never mind, figured it out. Not sure what it was, but it is fixed.

You had two catch clauses on the same try block catching exceptions of the same type. The second catch clause would never be executed.
