what is the advantage of interface over abstract classes?

Question

In Java, abstract classes give the ability to define both concrete and abstract methods whereas interfaces only give the ability to implement abstract methods. I believe overrid

Answer 1

You dont override an interface. You implement it.

Writing an interface gives implementors the ability to implement your interface and also other interfaces in addition to inheriting from a base class.

Abstract classes can be partially or fully implemented.Marking a class abstract just prevents you from instantiating an object of that type.
