Hi,
I was wondering how do you validate a inputbox so that only letters can be entered e.g. A --> Z

I know this validates it so only number can be entered, but what for the other way around?
Thanks Joe Kane

Check out the "Pattern" class in the java documentation.
 
It is sorta covered in the JavaRanch Style Guide.
