    Scanner input=new Scanner(System.in);

    double num1,num2,result=0;

    System.out.println("\t\t\tCalculator\n\nEnter First number:");

    num1=input.nextDouble();

    System.out.println("Enter Second number:");

    System.out.println("Enter an Operator(+ - * / %) :");

    input.nextLine();

    char operator=input.nextLine().charAt(0);

    switch(operator)

    {

    case '+':

    result=num1+num2;

    break;

    case '-':

    result=num1-num2;

    break;

    case '*':

    result=num1*num2;

    break;

    case '/':

    result=num1/num2;

    break;

    case '%':

    result=num1%num2;

    break;

   

    default:

    System.out.println("Invalid Operation.");

    }

    System.out.println(num1+" "+operator+" "+num2+" = "+result);

    }

}
