Multilevel Inheritance Example

This program demonstrates multilevel inheritance.

Problem Statement

Write a Java program to show multilevel inheritance among Person, Student, and Graduate.

Source Code

1	class Person {
2	String name;
3	}
4	class Student extends Person {
5	int age;
6	}
7	class Graduate extends Student {
8	String degree;
9	}
10	public class MultilevelInheritance {
11	public static void main(String[] args) {
12	System.out.println("Eduinq Multilevel Inheritance");
13	Graduate g=new Graduate();
14	g.name="Arun"; g.age=22; g.degree="MCA";
15	System.out.println("Name: "+g.name+", Age: "+g.age+", Degree: "+g.degree);
16	}
17	}

Program Output

Eduinq Multilevel Inheritance
Name: Arun, Age: 22, Degree: MCA

Explanation

Multilevel inheritance chains classes. - Graduate inherits from Student, which inherits from Person. - This creates a hierarchy where attributes flow down the chain. Conclusion: Shows how to implement multilevel inheritance.
