Java Program to calculating value using Scanner in Java

Using this Program we can calculate given value of a&b using scanner. This program will help to build the calculator. So read carefully and implement this program.


package com.indra;

import java.util.Scanner;

public class SystemUsingScanner {
static int a;
static int b;
static int c;

public static void main(String[] hh) {
Scanner obj = new Scanner(System.in);
for (int i = 0; i >= 0; i++) {
System.out.println("1 Addition");
System.out.println("2 Substraction");
System.out.println("3 Multiplication");
System.out.println("4 Division");
System.out.println("5 for close your calculator");
int op = obj.nextInt();
boolean close = false;///// use to check case 5 for close this program
switch (op) {

case 1:
System.out.println("Enter the value of a & b for Addition");
a = obj.nextInt();
b = obj.nextInt();
c = a + b;
System.out.println(c);
break;
case 2:
System.out.println("Enter the value of a&b for multiplication");
a = obj.nextInt();
b = obj.nextInt();
c = a - b;
System.out.println(c);
break;
case 3:
System.out.println("Enter the value of a&b for multiplication");
a = obj.nextInt();
b = obj.nextInt();
c = a * b;
System.out.println(c);
break;
case 4:
System.out.println("Enter the value of a&b for multiplication");
a = obj.nextInt();
b = obj.nextInt();
c = a / b;
System.out.println(c);
break;
case 5:
close = true;
break;
default:
break;
}
if (close) {        /// condition true then program will close
break;
}
}
}
}
