Intent of Mediator Design Pattern

The Mediator design pattern is intended to reduce the complexity of communication between multiple objects or classes in a system. It achieves this by providing a centralized mediator class that handles the interactions between different classes, thus reducing their direct dependencies on each other.

• Dependents

Intent of Observer Design Pattern

The Observer pattern in Java defines a one-to-many relationship between objects, ensuring that when one object updates its state, all dependent observers are notified and updated automatically, enhancing system responsiveness and modularity.
