Description

In some situations it is much easier if you can execute an action when you enter to or exit from a certain state regardless of which transition has caused it.
else you have to repeat the behavior in each entering or exiting transition.

Here some more information could be found:
http://en.wikipedia.org/wiki/UML_state_machine#Entry_and_exit_actions

here is a sample usage:

@onEntry(LOADED )
public void onEntryStart() {
System.out.println("On Start Entry");
}

@onExit(LOADED)
public void onEntryExit() {
System.out.println("On Start Exit");
}

I attach a candidate implementation.
