Program Listing


package demo;

import java.util.Scanner;



public class mdas {

public static void main(String[] args) {
    // create Scanner class object to  
      // read inputs
      Scanner scan = new Scanner(System.in);
  // Declare variables
      int num1=0, num2=0;
      char operator='\0';
 
      char choice= '\0';
   do {
      
 
       
      System.out.print("Enter the first Number      :  ");
      num1 = scan.nextInt();
      System.out.print("Enter the the Second number :  ");
            num2 = scan.nextInt();

      // read operator
      System.out.println("Available Operators"
+ "are::  (+ - * /)");
      System.out.print("Choose Oerator : ");
      operator = scan.next().charAt(0);

     
     if  (operator == '+') {

        System.out.println("The sum of  "+ num1 + " and " + num2 + " is " + (num1+num2)+".");
     } else if (operator == '-'){

    System.out.println("Invalid operator");
      } // end of switch-case
   
     System.out.print("Do you want to perform another calculation? [y-yes/n-no] : ");
    
     choice = scan.next().charAt(0);
     
     if (choice == 'N'|| choice == 'n') {
   
    System.out.print("End of Program");
    break;
