Requesting help for payroll program.

[ycg0771]

I'm trying to modify the following program so that it uses a class to store
and retrieve the employee's name, the hourly rate, and the number of
hours worked. Use a constructor to initialize the employee information,
and a method within that class to calculate the weekly pay. It seems that the more I read into this, the more confused I get. Any help will be greatly apreciated.
Here is my latest code...

// Payroll program that calculates an employee's weekly pay.
 
import java.util.Scanner; // program uses class Scanner
 
class EmployeeData {
    EmployeeData(String newName, float newHourlyRate, float newHoursWorked) {
        name = newName;  hourlyRate = newHourlyRate;  hoursWorked = newHoursWorked;
    }
 
    public String getName() { return name; }
    public float getWeeklyPay() { return hourlyRate * hoursWorked; }
 
    private String name;
    private float hourlyRate, hoursWorked;
} // end of EmployeeData class
 
public class Payroll3
{
   private String EmployeeData; // employee information for this Payroll
 
   // main method begins execution of java application
   public static void main( String args[] )
   {
        boolean stop = false; // This flag will control whether we exit the loop below
 
        // Loop until user types "stop" as the employee name:
        while (!stop)
        {     
            // create scanner to obtain input from command window
            Scanner input = new Scanner ( System.in );
 
            System.out.println();  // outputs a blank line
            System.out.print( "Please enter the employee name or 'stop' to end program: " ); // prompt
            String empName = input.nextLine(); // read employee name
 
            if ( empName.compareTo("stop") == 0) // Check whether user indicated to stop program
            {
                System.out.println( "Program ended." );
                stop = true;
            }
             else
             {
                   // User did not indicate to stop, so continue reading info for this iteration:
                EmployeeData employee;
                float hourlyRate; // first number to multiply
                float hoursWorked; // second number to multiply
                float weeklyPay; // product of hourlyRate and hoursWorked
 
                System.out.print( "Please enter hourly rate: $" ); // prompt
                hourlyRate = input.nextFloat(); // read hourly rate from user
                while (hourlyRate <= 0) // prompt until a positive value is entered
                {
                    System.out.print( "Hourly rate must be a positive value. " +
                       "Please enter the hourly rate again: $" ); // prompt for positive value for hourly rate
                    hourlyRate = input.nextFloat(); // read hourly rate again
                }
 
                  System.out.print( "Please enter hours worked: " ); // prompt
                  hoursWorked = input.nextFloat(); // read number of hours worked from user
                  while (hoursWorked <= 0) // prompt until a positive value is entered
                  {
                     System.out.print( "Hours worked must be a positive value. " +
                           "Please enter the hours worked again: " ); // prompt for positive value for hours worked
                      hoursWorked = input.nextFloat(); // read hours worked again
                  }
 
                 employee = new EmployeeData(empName, hourlyRate, hoursWorked);
                  ///weeklyPay = hourlyRate * hoursWorked; // multiply
 
                  System.out.print( employee.getName() ); // display employee name
                  System.out.printf( "'s weekly pay is: $%,.2f\n", employee.getWeeklyPay() );  // display weekly pay
 
        }
      }
 
   } // end method main
 
} // end class Payroll3

What appears to be the problem, the EmployeeData class seems to do everything you have asked....

I assume you need help with the main body of the program, but could you please specify what is the problem you are having....

I think we might be in the same class... I am trying to figure these things out too... I will try to help you as I get them...

To store the Employers's data, you neen an ArrayList not a String.

Thank you, but this outputs a note of "uses unchecked or unsafe operations".

Thank you. I wasn't doing too bad in this class until this past week. I was ill for three days and I guess it threw me off track more than I ever imagined.

I assume you need help with the main body of the program, but could you please specify what is the problem you are having....

You are correct. I thought I had a problem here, but after going through it once again, step by step, the code works as it should. I hate to admit it, but my husband must be right when he tells me that I make things harder than what they really are. I apologize for wasting everyone's time here.
Thank you.

No you did not waste anyone's time

Ok so I’m in this same class and your posts really helped allot. I just want to know how do I not plagiarize the work that was done by someone else if we all have to write the same application? I’m about to turn mine in and it’s almost a copy/paste of the code above even though I wrote it all out.

If you've written the code by yourself, I wouldn't be terribly worried about it. Some simple programs have just about 1 solution, and every code solving that problem will look similar, if not identical. As long as your code works and you know you've written it yourself and thought the whole process through thoroughly, I think you'll be fine.
