In my JtextField I would like to check if a user has typed in something other then a number.
Forexample a user types by mistake 'w' instead of 3 how can I detect this error???
Thanks Lisa

There's a example in Core Java vol 1 (chapter on swing).
It does'nt allow the user to type in anything other than a +ve integer.
