![]() So I thought of using Observable in composition than inheritance. Prefer composition over inheritance is a golden rule. In a real time application I may need that option to be used for business inheritance. I can extend only one class and I do not want to exhaust that option with this Observable class. As we all know, java does not support multiple inheritance. Using these APIs, Observable and Observer in real time application may not be possible most of time. Observable provides implementation for methods to register or unregister an Observer and to notify the Observer objects. Observable is a class which should be extended by a subject. Observer is an interface which needs to be implemented to observe the state change in a observable subject. This is not something new and these classes were available since JDK 1.0. JDK provides Observer and Observable classes as part of util package. ![]() Underlying data is same and when that data (subject) state changes all the different view are updated. Generally data is is shown in grid cells and as required different graphs, charts can be created for same data. Consider an excel sheet, data is shown to the user in different views.When multiple objects depend on state of one object and all these multiple objects should be in sync with the state of this one object then observer design pattern is the right choice to apply.Along with the notification, state is also passed in some implementation so that the observer need not query back to know the status. The above last two points are not strictly followed in observer design pattern implementation. Once the notification is received from subject, observers call the subject and get data that is changed.Subject just sends the notification saying the state has changed.Multiple observers can subscribe for notifications.Subject provides interface for observers to register and unregister themselves with the subject.Important Points on Observer Design Pattern Model view controller (MVC) architecture’s core uses the observer design pattern. Pattern involved is also called as publish-subscribe pattern. Objects that listen or watch for change are called observers and the object that is being watched for is called subject. When the state of subject changes, it notifies the observers. In observer design pattern multiple observer objects registers with a subject for change notification.
