Then the class with the bound property must call firePropertyChange whenever it changes the value of the bound property (i.e. in the set method of the property).

Any class which wants to be notified of changes to the bound property must implement the PropertyChangeListener and supply a method propertyChange that will be called with a PropertyChangeEvent. This method can use event methods getOldValue() and getNewValue.
