Answer 1

If you want to run your action manually, you can generate an ActionEvent and pass it into the actionPerformed method that your Action must implement, as the Action interface extends ActionListener.

Answer 2

Because an Action is an EventListener, you may want to consider implementing an EventListenerList as a way to expose methods that fire actions.

Answer 3

You can simply invoke the action event's method directly:

for(ActionListener a: buttonExample.getActionListeners()) {
    a.actionPerformed(new ActionEvent(this, ActionEvent.ACTION_PERFORMED, null) {
          //Nothing need go here, the actionPerformed method (with the
          //above arguments) will trigger the respective listener
    });
}
