Inheritance is a mechanism in which one class acquires the property of another class. For example, a child inherits the traits of his/her parents.

Inheritance enables reuse. It’s called inheritance because all the existing properties and methods of an original base (or super ) class are passed on to the newly created class, called an extended (or derived ) class. Another key principle of any OOP language is polymorphism .
What is overloading and overriding in Java with examples?
Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding occurs when two methods have the same method name and parameters. One of the methods is in the parent class, and the other is in the child class.
