Facade Design Pattern Explained With Simple Example: Structural Design Pattern Category
by The Facade design pattern provides a simple interface to a complex code in order to make the product easier to understand and use. This design pattern reduces the dependency of client code on the implementation of internal objects and since most of the product code uses the facade to hide the complexity of the system, thus allows the flexibility in developing the system. In this pattern, a single wrapper class known as “Facade” is implemented which contains a set of objects required by client.
