Interface and abstract class are both used for abstraction in object-oriented programming.

• An interface is a collection of abstract methods that define a contract for a class to implement.

• An abstract class is a class that cannot be instantiated and may contain abstract methods.

• Interfaces are used to achieve multiple inheritance in Java.

Polymorphism is the ability of an object to take on many forms.

• It allows objects of different classes to be treated as if they were objects of the same class.
