What is the difference between an interface and abstract class? An interface is a good example of loose coupling (dynamic polymorphism dynamic binding) An interface implements polymorphism and abstraction It tells what to do but how to do is defined by the implementing class
Implementing two interfaces in a class with same method. Which . . . If both interfaces have a method of exactly the same name and signature, the implementing class can implement both interface methods with a single concrete method However, if the semantic contracts of the two interface method are contradicting, you've pretty much lost; you cannot implement both interfaces in a single class then
c# - Class vs. Interface - Stack Overflow 0 In C#, multiple inheritance can be achived through Interface only Based on u r business requirement if there is a need that your class needs multiple inheritance going fwd, then use Interface else use class Also all members of Interfaces should be given defination in class i e interface members are must-implemented members
oop - When to use an interface instead of an abstract class and vice . . . An Interface is more of a high level architectural tool (which becomes clearer if you start to grasp design patterns) - an Abstract has a foot in both camps and can perform some of the dirty work too Why use one over the other? The former allows for a more concrete definition of descendants - the latter allows for greater polymorphism
