    Default Re: fixing these two errors

    Hello big_c and welcome to the Java Programming Forums

    You are getting the error because of this:

    PayCheck aPayCheck = new PayCheck([B]hourlyWage[/B], hours);
    hourlyWage is a double value and the PayCheck constructor is looking for an Integer value.

    You could try type casting the hourlyWage variable to Integer:

    import java.util.Scanner;
     
    /**
       This program calculates the pay of an employee.
    */
    public class PayCalculator
    {
       public static void main(String[] args)
       {
     
          Scanner in = new Scanner(System.in);
     
          System.out.println("Hourly wage: ");
          double hourlyWage = in.nextDouble();
     
          [B]int hourlyWageInt = (int)hourlyWage;[/B]
     
          System.out.println("Hours worked: ");
          double hours = in.nextDouble();
     
          PayCheck aPayCheck = new PayCheck([B]hourlyWageInt[/B], hours);
     
          System.out.println("Pay: "+ aPayCheck.getPay());
       }
    }

    Even with my code you are still getting the same error?

    That is strange because it is compiling fine for me...

    Please make sure you change:

    PayCheck aPayCheck = new PayCheck(hourlyWage, hours);

    to
    PayCheck aPayCheck = new PayCheck(hourlyWage[B]Int[/B], hours);

    From the errors that it is providing you, it looks like it isn't recognizing the PayCheck class. Are they in the same directory? If their not, then the program won't realize what you're trying to import with that command line.

    It wasn't the hourlyWage that was set as a double, it's the hours. So the hourlyWage is fine without the Int since you set it as an Int in the PayCheck class.

    Yes you should check to make sure the PayCheck class is in the same directory as this could also be causing the problem.

    Sorry EmeraldStones, I think you are wrong. If you look at the PayCalculator class, hourlyWage is infact set as double:

    double hourlyWage = in.nextDouble();

    And the PayCheck class constructor is looking for an Integer value and a double value in that order. The values passed to this constructor have to be Integer, Double.

    public PayCheck(int PayCheck, double hours) {

    You are trying to send:

    PayCheck aPayCheck = new PayCheck(hourlyWage, hours);
    And of course hourlyWage is a double value, not an Integer. You are sending double, double.

    This is 100% what is causing this error as you can clearly see in Eclipse:

    Are the PayCalculator & PayCheck classes both in your My Documents directory?

    This error is generated because it looks like the PayCheck class cannot be located.

    I can't see anything wrong with the code. In Eclipse it is all compiling fine.

    Could you attach a screen shot of your IDE including the error? This might help me to see what is going on.

    OK I can see your error!

    In PayCalculator you call aPayCheck.getPay()

    System.out.println("Pay: "+ aPayCheck.getPay());

    But getPay() doesn't exist in the PayCheck class.

    You have renamed getPay() to PayCheckgetPay()

    To fix the error, update the PayCalculator class with:

    System.out.println("Pay: "+ aPayCheck.[B]PayCheckgetPay()[/B]);

    Default Re: fixing these two errors

    There are a few reasons why this code did not fuction properly.

    The PayCheck value was always being passed as 0. Once that is corrected the variables need to be changed from int to double.

    Can you please explain the calculations for me? Please give me an example input for hours & hourly wage and the desired output.

    I'll post the updated code after..

    ok for hourly wage i used 7.15 and for hours i used 40 and 50(for overtime) the output should be 286 for 40 hours and for 50 it should be 536.25 if i used the right overtime percentage

    Oh I gotcha, I completely missed that line XD
    Ahh well. Well at least it's compiling the syntax now. This looks completely like an assignment I had to do for my Java course... I'm not certain as this assignment may be different, but ours had to print out the check value in a dollar format, and by the looks of what the code shows, maybe they can't enter more than 40 hours?

    I'm new to this whole java thing too so, I'm just imputing my thoughts to see if I know what I'm talking about XD

    As far as the hourly wage and overtime pay. For over 40 hours shouldn't it be (40*hourlyWage)+((hours-40)*hourlyWage*1.5)

    That way you calculate the standard 40 hours worked, plus the difference of the hours worked multiplied by the wage and then calculated as time and a half?

    and if that's the case as well, shouldn't the last line in the PayCalculator class be

    System.out.printf("Pay: "+ "1.2f" + aPayCheck.getPay())

    to display it in a dollar format?

    And as the overtime, if it is time and a half, I got the result to be $393.25...

    This is a learning experience for us both =D

    Thank you for the calculations EmeraldStones. They look correct to me.

    big_c, here is the fixed code:

            this.PayCheck = hourlyWage;
            this.hours = hours;
     
        }
     
        public double getPay()
     
        {
          [B]  if (hours <= 40) {[/B]
    [B]
                PayCheck = (PayCheck * hours);
     
            } else if (hours > 40) {
     
                PayCheck = ((40 * PayCheck) + (hours - 40) * (PayCheck * 1.5));
     
            }[/B]
     
            return PayCheck;
        }
     
        private double hourlyWage;
