Practical 3

Aim:- Write a program to enter two numbers and perform mathematical operations on them.

JAVA Code :-

import java.lang.*;

class cal

{

    public static void main(String args[])

    {

        int a,b,ans;

      

        a= Integer.parseInt(args[0]);

        b= Integer.parseInt(args[1]);

        switch(args[2])

        { 

           case "+":

                       ans=a+b;

            System.out.println("Add= "+ans);

                        break;

               case "-":

                        ans=a-b;

                        System.out.println("Sub= "+ans);

                        break;

              case "*":

                        ans=a*b;

                        System.out.println("Mul= "+ans);

                        break;

              case "/":

                        ans=a/b;

                        System.out.println("Div= "+ans);

                        break;

       }

     }

}

Output:-
