Final answer:
The Facade pattern provides a simplified interface to a complex system of classes. It promotes loose coupling and improves code readability.
Step-by-step explanation:
The Facade pattern is a software design pattern that provides a simplified interface to a complex system of classes, making it easier to use and understand. It acts as a unified interface for a set of interfaces in a subsystem. By providing a higher-level interface that hides the complexities of the subsystem, the Facade pattern promotes loose coupling and improves code readability.
For example, imagine you have a car with various subsystems like the engine, transmission, and electronics. The Facade pattern allows you to create a CarFacade class that wraps these subsystems and exposes simplified methods like start(), stop(), and accelerate(). This abstracts away the complexities of the individual subsystems and provides a convenient way to interact with the car as a whole.
