Slip 11 - A) Write a menu driven java program using command line arguments for the following: 1. Addition 2. Subtraction 3. Multiplication 4. Division.

Solution :

import java.util.Scanner;

public class Slip11A {

    public static void main(String args[]){

        int a,b,n;

System.out.println("Enter 1 : Additon" + '\n' + "Enter 2 : Substraction" + '\n' + "Enter 3 : Multiplication" + '\n' + "Enter 4 : Division");

        Scanner dr=new Scanner(System.in);

        try {

            a = Integer.parseInt(args[0]);

            b = Integer.parseInt(args[1]);

            System.out.print("Enter Number : ");

            n = dr.nextInt();

            switch(n){

                case 1:  

                System.out.println(a + " + " + b + " = " + (a+b));

                break;

                case 2:  

                System.out.println(a + " - " + b + " = " + (a-b));

                break;

                case 3:  

                System.out.println(a + " * " + b + " = " + (a*b));

                break;

                case 4:  

                System.out.println(a + " / " + b + " = " + (a/b));

                break;

            }

        } catch (Exception e) {}

    }

}

Output:
