How are Observer and Observable used?

Answer Posted / guest

Objects that subclass the Observable class maintain a list
of observers. When an Observable object is updated it
invokes the update() method of each of its observers to
notify the observers that it has changed state. The
Observer interface is implemented by objects that observe
Observable objects.
