The client class is missing, but it will use both the ConcreteSubject and ConcreteObserver classes. Here’s a simple implementation of a push model version of all of these. Remember, it’s a push model because the ConcreteSubject object is notifying all the Observers whether they request it or not.

First, we create the Subject interface that tells us how to register, remove, and notify the Observers:

public interface Subject {

public void addObserver(Observer obs);

public void removeObserver(Observer obs);

public void notifyAllObservers();

}
