Explanation:

import java.util.Scanner;

public class Calculate

{

public static void main(String[] args)

{

int m, n, opt, add, sub, mul;

double div;

Scanner s = new Scanner(System.in);

System.out.print("Enter first number:");

m = s.nextInt();

System.out.print("Enter second number:");

n = s.nextInt();

while(true)

{

System.out.println("Enter 1 for addition");

System.out.println("Enter 2 for subtraction");

System.out.println("Enter 3 for multiplication");

System.out.println("Enter 4 for division");

System.out.println("Enter 5 to Exit");

opt = s.nextInt();

switch(opt)

{

case 1:

add = m + n;

System.out.println("Result:"+add);

break;

case 2:

sub = m - n;

System.out.println("Result:"+sub);

break;

case 3:

mul = m * n;

System.out.println("Result:"+mul);

break;

case 4:

div = (double)m / n;

System.out.println("Result:"+div);

break;

case 5:

System.exit(0);

}

}

}

}
