Facade pattern is often needed when there is a large number of interdependent classes or because parts of the code are unavailable. Facade pattern is one of the structural design.
Facade Pattern Java. The facades act as communication interfaces between the individual layers, increasing flexibility and the possibility of extension and adaptation of components. Facade design pattern is used to help client applications to easily interact with the system.

It hides the complexities of large system and provides a simple interface to client. A facade pattern says that just just provide a unified and simplified interface to a set of interfaces in a subsystem, therefore it hides the complexities of the subsystem from the client. This supports loose coupling by hiding the complex details via a simple interface.

This pattern introduces a component called facade, which is a simplified interface component. Facade design pattern is a commonly used software design pattern that is used to structure systems in a way that helps in reducing complexity. Url class is another facade that exposes the openstream () method hiding all involved details. You can also call it a logical extension.

It is an example of facade pattern. Facade design pattern is another pattern from structural design pattern category. The facade is a structural design pattern and one of the gang of four design patterns. In facade design pattern, the main idea is to have one point from calling many methods created in more classes. It is usually composed of all.
