Interface is like "a wall in the building" ... if our program needs to use multiple inheritance, there code reusability will happen..so instead of writing so many multiple inheritance's we will use interface.

we can not inherit more than one class in single class. Instead of multiple inheritance we use interface. If you should define one method in derived class we use interface.
