Answer 2

The need of interface in any system is described below:

• An interface establishes the capabilities of the classes. Every abstract method declared in an interface will have implementation when a class complies with the interface's requirements.
• Interface identifies a collection of typical actions. These behaviors are accepted by the classes that implement the interface, and they offer their own implementation of the behaviors.
• As opposed to the actual implementation, this enables you to program at the interface. An interface's primary function is to establish a communication contract between two objects.
• Knowing that a class implements an interface means you are aware of the fact that the class has actual concrete implementations of the methods declared in the interface.
• In other words, two objects can communicate based on the interface's contract rather than their own specific implementation.
