Inheritance in java is a mechanism in which one object acquires all the properties and behaviors of the parent object.
To learn more about Inheritance, you can try solving this challenge first.
Task: A class named Arithmetic with a method named add that 2 takes integers as parameters and returns an integer denoting their sum.
A class named Adder that inherits from a super class named Arithmetic. Your classes should not 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
Source code
import java.io.*;

class Arithmetic {
int add (int a, int b) {
return a + b;
}
}
class Adder extends Arithmetic {}
public class Solution{
public static void main(String []args){
Adder a = new Adder();
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");
}
}
