Explanation:
Detailed explanation-1: -The main objective of facade design pattern is to provide a simple interface before a complex system. So that the user or client can access the simple interface without knowing the complexity of its sub-system. Facade design patterns are mostly used to hide the dependencies involved in a system from the user.
Detailed explanation-2: -Use the Facade pattern when you need to have a limited but straightforward interface to a complex subsystem. Often, subsystems get more complex over time. Even applying design patterns typically leads to creating more classes.
