What is the purpose of the Facade pattern in software development?

The Facade pattern is designed to simplify interaction with a complex system or set of classes. It provides a single, simple interface, hiding the complexity of the internal implementation.

This helps to:

• Reduce dependency of the client on implementation details.
• Simplify the use of the subsystem.
• Improve code readability and maintainability.

For example, in Android, you can create a facade for network operations that internally uses several classes for connection setup, response handling, and error processing, while the client code only calls the facade methods.
