Java Inheritance with Examples:

What is a Inheritance ?

The derivation of one class from another class is called Inheritance.

Type of inheritance :

A class that is inherited is called a super class.

The class that does the inheriting is called as subclass.

In above figure all class A is super class.

A subclass inherits all instance variables and methods from its super class and also has its own variables and methods.

One can inherit the class using keyword extends.

Syntax :

Class subclass-name extends super class-name

{

// body of class.

}

In java, a class has only one super class.

Java does not support Multiple Inheritance.

One can create a hierarchy of inheritance in which a subclass becomes a super class of another subclass.

However, no class can be a super class of itself.

Java Inheritance example program :


 


Output :
Multiplication is  30
Note : Private members of super class is not accessible in subclass,
           super class is also called parent class or base class,
           subclass is also called child class or derived class.
