Question

I have a Java question. (I'm using BlueJ.) I'm trying to program something that calculates pay roll. Most of it works, but I've identified two parts that don't: It labels all salaries as "Fulltime" no matter how many hours worked I input, and the do/while loop does something weird.

The if/else statement I have for the fulltime vs part time is:

if (hoursWorked < 40.0) {
position = partTime;
} else if (hoursWorked >= 40.0 || hoursWorked <= 168.0) {
position = fullTime;
} else if (hoursWorked > 168.0) {
System.out.println("Error. Please try again.");
}

And the do/while loop ends with:

} while (employeeName != "Exit");

When the loop comes back around, it prints:

Employee name: Base pay rate:

And then fails no matter what I put. For that part I have:

System.out.print("Employee name: ");
employeeName = read.nextLine();
System.out.print("Base hourly pay: ");
baseSalaryPay = read.nextDouble();
System.out.print("Hours worked: ");
hoursWorked = read.nextDouble();

What do I need to fix?

Answer 1

There are two major fix here:

1. The != operator,  In java will tell whether two objects are equal or not.
   here in your case, you need to use .equals function of string class. So the while part will be
   
   } while (!employeeName.equals("Exit"));
   
   
2. The 2nd problem is your else if condition which will always be true
   
   else if (hoursWorked >= 40.0 || hoursWorked <= 168.0)
   
   Take few example,
   1.  hoursWorked = 10 =>> (hoursWorked >= 40.0) = false, (hoursWorked <= 168.0) = true, so false || true = true, so result is true
   
   2.  hoursWorked = 120 =>> (hoursWorked >= 40.0) = true, (hoursWorked <= 168.0) = true, so true || true = true, so result is true
   
   3.  hoursWorked = 230 =>> (hoursWorked >= 40.0) = true, (hoursWorked <= 168.0) = false, so true || false = true, so result is true
   
   
   So the problem is with you condtion you need to change it to && instead of ||, Likeelse
   
   if (hoursWorked >= 40.0 && hoursWorked <= 168.0)
