Is this a Swing application, and are you using a JButton? Or is this AWT? SWT? Other? Details can mean a lot I'm afraid. If Swing, then you can set the root pane's default button via its setDefaultButton(JButton defaultButton) method.

Perhaps if you tell us more, we can tell you more. Much luck!

Read about the ActionListener interface; you have to implement that interface and register it at your JButton. The JButton will call it when it is pressed.

kind regards,
