Palak enters a coding competition she wants to write code to pass down values from one class to another. Which of following concept should she use to do so ?

A. Inherits

B. Extends

C. Construct

D. All of the mentioned

Answer : C. Extends

Explanation:

  • A class in Java can extend another class to become a subclass. When class B extends the class A, B becomes subclass (child) and A becomes superclass (parent). A subclass can reuse all the features of the parent class and code reuse is a major reason for extending a class
Inheritance in Java
