The idea behind inheritance in java is that you can create new classes that are built upon existing classes. When you inherit from an existing class, you can reuse methods and fields of parent class, and you can add new methods and fields also
Inheritance represents the IS-A relationship, also known as parent-child relationship
Why use inheritance in java
