A Scenario where one class is inheriting/extending the bahavior of another class which in turn is inheriting behavior from yet another class.
Ex: public class Automobile {…}
Public class Car extends Automobile {…}
Public class Ferrari extends Car {…}
This multilevel inheritance actually has no limitations on the number of levels it can go. So as far as java goes, it is limitless. But for maintenance and ease of use sakes it is better to keep the inheritance levels to a single digit number.
Single Inheritance Multiple Inheritance Multilevel Inheritance
Grandfather-father-child relationship is an example for multi level inheritance..
there are several type of inheritance are exist like 1. single inheritance 2. double inheritance 3. multiple 4. multilevel 5. heirarchical inheritance
struct employee { }; struct supervisor : employee { // single inheritance -- a supervisor inherits all the public and protected properties of an employee. }; struct manager : supervisor { // multilevel inheritance -- a manager inherits all the public and protected properties of a supervisor (and therefore an employee). };
Multiple inheritance, as the name 'multiple' suggests, is one where more than one(multiple) super class is inherited by one sub-class. It can be represented as:A B C\ | /DOn the other hand, in case of multilevel inheritance; the superclass is inherited by a sub-class which is in turn inherited by another class leading to the different level. It can be represented as:A|B|CHowever in asp, multiple inheritance is not supported.
Multilevel InheritanceA Scenario where one class is inheriting/extending the bahavior of another class which in turn is inheriting behavior from yet another class.Ex: public class Automobile {…}Public class Car extends Automobile {…}Public class Ferrari extends Car {…}This multilevel inheritance actually has no limitations on the number of levels it can go. So as far as java goes, it is limitless. But for maintenance and ease of use sakes it is better to keep the inheritance levels to a single digit number.
Because it is one of the most important and widely used inheritance concepts in Java. In multi level inheritance a class directly inherits features from one class and indirectly inherits features form other classes that are in the inheritance hierarchy.

single level inheritance eg ( class B extends Class A) Multilevel inheritance eg( class C extends class B and class B extends class A) multiple inheritance Class C inherits Class A features as well as Class B featues.This type of inheritance is not allowed in JAVA.
In java we can implement more than one interfaces for a single class but we can't extend a class to more than one super class so ,java indirectly supports multiple inheritance.
Multiple Inheritance : we can inherit more than one class in the same class. Multi-Level Inheritance: where one class can inherit only one base class and the derived class can become base class of some other class.

You need to use them only if you want to have some i/o operations in your code.
