- The SubClass uses the ‘extends’ keyword to inherit all accessible fields and methods from the SuperClass. This is the basic usage of ‘extends’ in Java.
- The extends keyword plays a significant role in implementing the Inheritance concept in Java. Let’s start discussing the extends keyword with examples.

- Sometimes parent class can be called superclass or base class. Java extends keyword is used to define the IS-A relationship in java.
- Polymorphism is a fundamental concept in object-oriented programming, and the extends keyword is instrumental in its implementation in Java.
