Answer / nashiinformaticssolutions
Objects that inherit the "Observable class" take care of a list of "observers."
When an Observable object gets upgraded, it calls the update() method of each of its observers.
After that, it notifies all the observers that there is a change of state.
The Observer interface gets implemented by objects that observe Observable objects.
