Answer
The Observer Pattern allows an object to notify changes to other objects.
This pattern is useful for implementing event-driven systems in Java. For example, in an e-commerce platform, the Observer Pattern can update order status notifications. When an order is shipped, all observers (like email notification services) are notified and can react accordingly.
