Understanding the Facade Design Pattern in Java
The Facade Design Pattern is a structural design pattern that provides a simplified interface to a complex system such as a library, framework, or a set of classes. It hides the complexities of the system and provides the client with an easier way to access functionalities. What is the Facade Design Pattern? The Facade Pattern offers a unified interface to a set of interfaces in a subsystem. It defines a higher-level interface that makes the subsystem easier to use by encapsulating the interactions with multiple classes behind a single facade class. Real-World Analogy: Food Delivery App Consider a food delivery app like Zomato. The app serves as a facade that simplifies interactions between customers, restaurants, delivery teams, and delivery partners. Instead of customers interacting separately with all these entities, the app provides a single interface to place an order, which internally manages the complex processes like order preparation, assignment of delivery persons, a...
