Personally, I would suggest using four fields instead of one, where each
individual field can contain values ranging from 000 to 255 and perhaps
typing the third digit could even auto-tab out to the next field.
It would be far easier to write a single JTextField subclass that
accepts only numeric input and only a max set of digits, etc. You can
easily display these in such a way that the dots appear between them on
other components. And with a little experimentation, you might even be
able to set up other restrictions if needed, like not allowing 000 in
