```
{
```

    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);
```
```
            }
```
```
        }
```
```
    }
```
```
}
```
