This
interface
defines the method that an object must implement if it wants to be
notified when a preference key/value pair is added to, removed from,
or changed in a Preferences object. After any such
change, the Preferences object passes a
PreferenceChangeEvent object describing the change
to the preferenceChange( ) method of any
PreferenceChangeListener objects that have been
registered through the
Preferences.addPreferenceChangeListener( ) method.
