You can attach a listener to the text field ... counting the number of letters typed ... and then when it becomes 6 ... you can insert spaces as you like.

I'm not sure of what your coding? An applet or an application. If it is an applet this will get you on the right path to adding an actionListener, however, I'm not gonna code it all. Gotta have a little drama right?

public class yourClassName extends Applet implements ActionListener 
      {
           TextField yourTextField = new TextField(" ", 6);

        public void init()
          {
                  yourTextField.addActionListener(this);
}
         public void actionPerformed(ActionEvent e)
       {
        /* This is where you do the coding of what you want..
If the user hits enter when focus is on yourTextField *this* event will be executed.....  Dramatic right?*/
}
}
