# HackerRank Java Inheritance II problem solution

In this HackerRank Java Inheritance II problem in the java programming language you need to write the following two classes:

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 inherits from a superclass named Arithmetic.

Your classes should not be public.

## HackrRank Java Inheritance II problem solution.

```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){
int sum = a + b;
return sum;
}
}

public int callAdd(int a, int b){
}
}

public class Solution{
public static void main(String []args){
// Create a new Adder object

// 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:
}
}
```

## Second solution

```import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;

class Arithmetic {
Arithmetic() {}
}

int add(int a, int b) {
return a + b;
}
}

public class Solution{
public static void main(String []args){
// Create a new Adder object

// 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:
}
}
```

### The solution in Java 8 programming.

```import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;

class Arithmetic {
Arithmetic() {}
}

int add(int a, int b) {
return a + b;
}
}

public class Solution{
public static void main(String []args){
// Create a new Adder object
