A Java interface is an example of:
A) encapsulation
B) abstraction
C) polymorphism
D) all of the above
Java Interface
A reference type in Java that can contain only method signatures and static fields, used to define a contract for classes to implement.
Encapsulation
Encapsulation is an object-oriented programming concept involving the bundling of data with the methods that operate on that data, restricting direct access to some of the object's components.
Abstraction
A fundamental concept in object-oriented programming that hides the complexity of a system by displaying only essential features to the user, allowing focus on what an object does instead of how it does it.

Final Answer :
B
Explanation :
A Java interface is an example of abstraction as it defines a set of actions or behaviors without specifying how those actions will be implemented in the implementing class. Encapsulation and polymorphism are also fundamental concepts in Java programming but are not directly related to interfaces.
