Problem Name: Java Inheritance II

Problem Link:

In this HackerRank Functions in Java programming problem solution,

Write the following code in your editor below:

  1. A class named Arithmetic with a method named add that takes 2 integers as parameters and returns an integer denoting their sum.
  2. A class named Adder that inherits from a superclass named Arithmetic.

Your classes should not be be public.

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 2 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

        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");
