- oop - What is the definition of interface in object oriented . . .
An interface promises nothing about an action!

- c# - Class vs. Interface - Stack Overflow
But Interface is a contract which tells its implantations to provide if it is not an abstract class And the One important difference between a class and interface is that class inheritance will give relation between two common subclasses Where as Interface implementation gives a relation between two uncommon classes
