import java.util.Scanner;
public class Calculator {
public static void main(String[] args) {
double num1;
double num2;
double ans;
char op;
Scanner reader = new Scanner(System.in);
System.out.print("Enter two numbers: ");
num1 = reader.nextDouble();
num2 = reader.nextDouble();
System.out.print("
Enter an operator (+, -, *, /): ");
op = reader.next().charAt(0);
switch(op) {
case '+': ans = num1 + num2;
break;
case '-': ans = num1 - num2;
break;
case '*': ans = num1 * num2;
break;
case '/': ans = num1 / num2;
break;
default: System.out.printf("Error! Enter correct operator");
return;
}
System.out.print("
The result is given as follows:
");
System.out.printf(num1 + " " + op + " " + num2 + " = " + ans);
}
}
