Simple hierarchical inheritance program in java?

Answer 1

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 "Rocky";

}

}

public class B extends A {

public int getAge() {

return 24;

}

}

public class C extends B {

public String getAddress(){

return "North Carolina, USA";

}

}

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:

Rocky

24

North Carolina, USA

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.

Answer 2

public class A {

...

}

public class B extends A{

...

}

public class C extends B {

...

}

This is a simple hierarchical inheritance. The class C extends class B but since the class B extends A, class C indirectly extends class A also.

Answer 3

This is the scenario wherein your java code exhibits traits of more than one of the inheritance types:

Public class FerrariF12011 extends Ferrari implements Car, Automobile {…}

The above is a combination of both single and multiple inheritance.
