Key Component of Facade Method Design Pattern in Java
The key components of the Facade Method Design Pattern in Java:
- Subsystem:
- Represents the complex part of the system that the Facade aims to simplify.
- Comprises multiple classes and interfaces that collaborate to provide a set of functionalities.
- Clients typically should not interact with the Subsystem directly, but only through the Facade.
- Facade:
- The heart of the pattern.
- Acts as a simplified, unified interface to the Subsystem.
- Clients interact exclusively with the Facade, not with the underlying Subsystem classes.
- Typically has methods that delegate calls to appropriate classes within the Subsystem, hiding their complexity.
- Client:
- Represents any code that needs to utilize the Subsystem’s functionality.
- Interacts solely with the Facade, unaware of the Subsystem’s internal structure.
- Benefits from the simplified interface provided by the Facade, making code more concise and maintainable.
Facade Method Design Pattern in Java
Facade Method Design Pattern is a structural design pattern that provides a simplified interface to a complex subsystem. It acts as a “front door,” concealing the internal complexity of the subsystem and making it easier for clients to interact with it.
