public interface ListenableList<E>
extends java.util.List<E>

This interface defines a listenable version of a List.

To be notified of items being added to or removed from this list, provide an implementation of ListChangedListener via the addListChangedListener(ListChangedListener) method. When this listener is called back, you will be provided with a ListChangedEvent instance containing the items added or removed and the index at which they were added or removed.
