 Java Inheritance II Hackerrank Solution

For Explanation Watch Video:

Input Format

You are not responsible for reading any input from stdin; a locked code stub will test your submission by calling the add method on an Adder object and passing it  integer parameters.

Output Format

You are not responsible for printing anything to stdout. Your add method must return the sum of its parameters.

Sample Output

The main method in the Solution class above should print the following:

My superclass is: Arithmetic
42 13 20

Code:

import java.io.*;

import java.util.*;

import java.text.*;

import java.math.*;

import java.util.regex.*;

class Arithmetic{

    public int add(int a,int b){

        return a+b;

    }

}

class Adder extends Arithmetic{

    

}

public class Solution{

    public static void main(String []args){

        // Create a new Adder object

        Adder a = new Adder();

        

        // Print the name of the superclass on a new line

        System.out.println("My superclass is: " + a.getClass().getSuperclass().getName());  

        

        // Print the result of 3 calls to Adder's `add(int,int)` method as 3 space-separated integers:

        System.out.print(a.add(10,32) + " " + a.add(10,3) + " " + a.add(10,10) + "\n");

     }

}
