Problem with KeyListener

[majidmehul@xxxxxxxxxxx (mehul mehta)]

There is a more elegant way to control
what goes into your text field. Try
extending a PlainDocument and then use
it as the model for your text field.
You can then control the text field
contents by overriding insertString.
Look at the API documentation of JTextField
for an example.
