text field only accept numeric input

Question

I have a jframe with a text field. I want to ask how can only accept input text field containing numbers, so when users enter the letters will not be accepted

have a look into the tutorial referenced in the [swing tag wiki](http://stackoverflow.com/tags/swing/info) - it has more than one chapter dedicated to textfields and how-to achieve basic goals :-) — kleopatra, Nov 14 '12 at 09:06
