. Typically implemented with a subclass. If necessary, the specific observer role can save a reference to a specific topic role.The following is the sample code:/** * Abstract Theme characters * @author Dream * */public interface watched {public void Addwatcher (Watcher watcher);p ublic void REMWATC Her (watcher watcher);p ublic void Notifywatcher (String str);}/** * Abstract Viewer role * @author Dream * */public interface Watcher {public void updat

The event source, the U-layer, is able to send messages to the service layer, where we will put this c
