How do I programmatically send an ActionEvent (eg button pressed/ACTION_PERFORMED) to a JButton?

I know of:

button.doClick(0);

and

button.getModel().setArmed(true);
button.getModel().setPressed(true);
button.getModel().setPressed(false);
button.getModel().setArmed(false);

But isn't it possible to directly send it an ActionEvent?

EDIT: This is not production code, it's just a little personal experiment.

You can get a button's ActionListeners, and then call the actionPerformed method directly.

ActionEvent event;
long when;

when  = System.currentTimeMillis();
event = new ActionEvent(button, ActionEvent.ACTION_PERFORMED, "Anything", when, 0);

for (ActionListener listener : button.getActionListeners()) {
    listener.actionPerformed(event);
}
