From Java 1.5 or lower version, can an Action be used for JCheckBox &
JCheckBoxMenuItem pair or JToggleButton & JCheckBoxMenuItem pair?
JCheckBox, JCheckBoxMenuItem, JToggleButton and JCheckBoxMenuItem all have a constructor taking an Action. They also have a setAction(Action) method inherited from AbstractButton.

Java 1.6 has Action.SELECTED_KEY but 1.5 doesnt have.
So what?

Also how to execute an Action from program? like JButton has a
doClick method. I want to execute an action from program even when the
actual button or menuitem is removed from gui, thus i dont have an
reference for the actual gui component.
You can do
Action a = ...;
ActionEvent e =
new ActionEvent(this, ActionEvent.ACTION_PERFORMED, "bla";
a.actionPerformed(e);
