Facade
Save
Facade is a structural design pattern that provides a simplified interface to a complex subsystem. The facade pattern can be used to hide the complexity of a subsystem from the rest of the application, making it easier to use and maintain.
Benefits of Using Facade
There are many benefits to using the facade pattern, including:
- Reduced complexity: The facade pattern can help to reduce the complexity of a system by hiding the details of the subsystem from the rest of the application.
- Improved maintainability: The facade pattern can make it easier to maintain a system by encapsulating the details of the subsystem in a single class.
- Increased flexibility: The facade pattern can make it easier to change the implementation of a subsystem without affecting the rest of the application.
- Improved testability: The facade pattern can make it easier to test a system by providing a single point of contact for the subsystem.
When to Use Facade
The facade pattern is a good choice when you need to:
- Simplify the interface to a complex subsystem.
- Hide the details of a subsystem from the rest of the application.
- Make it easier to change the implementation of a subsystem.
- Improve the testability of a system.

How to Use Facade
To use the facade pattern, you will need to create a facade class that provides a simplified interface to the subsystem. The facade class should be responsible for managing the interaction between the client and the subsystem.
Here is an example of how to use the facade pattern in Java:
public class Facade {
private Subsystem1 subsystem1;
private Subsystem2 subsystem2;
public Facade() {
this.subsystem1 = new Subsystem1();
this.subsystem2 = new Subsystem2();
}
public void operation() {
subsystem1.operation1();
subsystem2.operation2();
}
}
In this example, the Facade class provides a simplified interface to the Subsystem1 and Subsystem2 classes. The Facade class is responsible for managing the interaction between the client and the subsystems.
Online Courses on Facade
