Usually in actionPerformed(java.awt.event.ActionEvent myEvent) you
determine the object the event came from by calling myEvent.getSource().
Depending on that you usually divert to a method which actually performs
the action for your object, e.g.

if (myEvent.getSource == myButton) actionMyButton(myEvent);

so the method actionMyButton(java.awt.event.ActionEvent myEvent) is the
one you want to call if the "Enter" Key is pressed. The way to do this
is really simple: in the method you process the Enter key with, you
simply create a new ActionEvent (which is no more than an object after
all) and hand it to the actionMyButton method. Even better, you can hand
it to the actionPerformed method and let that one pass it to
actionMyButton.

here's how to call actionPerformed:

java.awt.event.ActionEvent buttonEvent = new
java.awt.event.ActionEvent(myButton,
java.awt.event.ActionEvent.ACTION_PERFORMED, null);
actionPerformed(buttonEvent);

This is effectively nothing more than pressing the button. AFAIK it's
the only way to achieve what you want.
