Calculator Implementation

The interface Calculator defines the following methods.

public interface Calculator {
    int add(int x, int y);
    int subtract(int x, int y);
    int mutiply(int x, int y);
    int divide(int x, int y);
}

Define the class NormalCalculator so that it implements the interface Calculator.

Input Format:
First line contains x.
Second line contains y.

Output Format:
The first line contains the sum of x,y
….
…
The fourth line contains the value of x/y

Boundary Conditions:
1 <= x,y < = 99999

Example Input/Output 1:
Input:
10
5

Output:
15
5
50
2

public class NormalCalculator implements Calculator{

    int add(int x,int y)
    {
      return x+y;
    }
    int subtract(int x,int y)
    {
      return x-y;
    }
    int multiply(int x,int y)
    {
      return x*y;
    }
    int divide(int x,int y)
    {
      return x/y;
    }

}//End of class NormalCalculator
