Inheritance in Java

In OOPs we can create the different classes and functions according to our need and from the base class we can derived the classes so, using the Inheritance the derived class can access the behaviour and property of  base class .Using Inheritance the code reusability increases i.e if we want to create a new class and there is already a class which include some of the data we want then we can derive the new class from existing class and time requirement for process can be reduced and debugging of code becomes easy.

There are five types of Inheritance supported by Java:

Single Inheritance:

In a single inheritance, sub class inherit the features of one superclass. In below figure 'A' is super class and 'B' is a sub class which is inheriting the features from super class.

Multilevel Inheritance:

In multilevel inheritance derived class will be ineheriting a base class and it will act as a base class to another class .Here 'A' is base class and 'B' is inheriting features from 'A' and 'B' is base class as well for class'C'.

Hierarchical Inheritance:

In Hierarchical Inheritance there is only one super class and multiple sub classes inherit properties from single super class.

Multiple Inheritance:

In Multiple Inheritance the one base class can inherit properties from more than one super class. In Java we can achieve Multiple Inheritance only with Interfaces

Hybrid Inheritance:

It is the mix of all types of inheritance,Java does not support Hybrid Inheritance we can achieve it through interfaces like multiple inheritance
