Write program java explain use abstract class multilevel inheritance?

Java

Multilevel inheritance is a Java feature where the properties of a class are inherited by a class which extends one or more classes which extend its features...

Example:

public class A {

public String getName(){

return "Vijay";

}

}

public class B extends A {

public int getAge() {

return 24;

}

}

public class C extends B {

public String getAddress(){

return "Utter Pradesh,India";

}

}

public class D extends C {

public void print {

System.out.println(getName());

System.out.println(getAge());

System.out.println(getAddress());

}

}

This method would print the following in the console:

Vijay

24

Pradesh,INDIA

Here in class D you are calling methods that are available inside classes A, B & C. Though D extends only class C, it would in turn inherit the properties of the classes extended by C and its parents.

This is multi level inheritance.
