 8. Write a Java program to accept two numbers using command line argument and calculate addition, subtraction, multiplication and division.

import java.util. *;
class calculator{
    public static void main(String agrs[]){
        Scanner sc = new Scanner(System.in );
        int ans, ch;
        System.out.print("Enter first value:");
        int a =sc.nextInt();
        System.out.print("Enter sec. value:");
        int b =sc.nextInt();
            
        while (true){
            System.out.println("\n\n");
            System.out.println("Press 1 for Addition :");
            System.out.println("Press 2 for Substraction :");
            System.out.println("Press 3 for Multiplication:");
            System.out.println("Press 4 for Division:");
            System.out.println("press 0 for exit");
    
            System.out.print("\n\n Enter your choise: ");
            int x = sc.nextInt();
    
            switch(x){
                case 1:
                    ans = a + b;
                    System.out.println("Addition is: " + ans);
                    break;
                
                case 2:
                    ans = a - b;
                    System.out.println("Substraction is:" + ans);
                    break;
                
                case 3:
                    ans = a * b;
                    System.out.println("multiplication is :" + ans);
                    break;
                
                case 4:
                    ans = a / b;
                    System.out.println("division is :" + ans);
                    break;
                
                case 0:
                    System.exit(0);
                }
            
            }
    }
}

Enter first value:4
Enter sec. value:2

Press 1 for Addition :
Press 2 for Substraction :
Press 3 for Multiplication:
Press 4 for Division:
press 0 for exit

Enter your choise: 1
Addition is: 6
