/* The Payroll Class Represents Payroll data for a user entered employee */

public class Payroll
{
//Fields
private String employeeName; //The Employees Name
private int idNumber; //The Employees ID number
private double hourlyPayRate; //How much the Employee makes per hour
private double hoursWorked; //How many hours the employee worked in one week

//Constructor accepts arguments for the employees name, ID Number, pay rate
//and the amount of hours worked.

public Payroll (String employeeName, int idNumber, double hourlyPayRate,
double hoursWorked)

{
employeeName = "ename";
idNumber = number;
hourlyPayRate = hpr;
hoursWorked = hw;
}

//The setEmployeeName method accepts an argument for the employees name

public double getHoursWorked()
{
return hoursWorked;
}
//Calculate gross pay

public double getGrossPay()

{
return (hoursWorked * hourlyPayRate);
}


}



I get this error, i highlighted the lines where these are since the code got all fucked up when i copy pasted it into here:



----jGRASP exec: javac -g Payroll.java
Payroll.java:19: cannot find symbol
symbol : variable number
location: class Payroll
idNumber = number;
^
Payroll.java:20: cannot find symbol
symbol : variable hpr
location: class Payroll
hourlyPayRate = hpr;
^
Payroll.java:21: cannot find symbol
symbol : variable hw
location: class Payroll
hoursWorked = hw;
^
3 errors


Here is the program i plug this into, which seems to be running fine:

//Import scanner utility

import java.util.Scanner;

//This program runs a test of the Payroll Class

public class PayrollTest
{
public static void main(String[] args)
{

String testName; //Hold employee name
int testID; //Hold employee ID Number
double testHPR; //Hold employee Hourly Pay Rate
double testHW; //Hold employee Hours Worked

//Create a Scanner object for keyboard input.

Scanner keyboard = new Scanner(System.in);

//Get the employee name

System.out.print("What is the employees name?: ");
employeeName = keyboard.nextLine();

//Get the employee ID Number

System.out.print("What is the employees ID Number?: ");
idNumber = keyboard.nextInt();

//Get the employees hourly wage

System.out.print("What is the employees Hourly Pay Rate?: ");
hourlyPayRate = keyboard.nextDouble();

//Get the employees amount of hours worked.

System.out.print("How many hours did the employee work?: ");
hoursWorked = keyboard.nextDouble();


//Calculate Hours worked times hourly wage



//Create an instance of the Payroll Class
//passing the data that was entered as arguements to the constructor

Payroll data = new Payroll(testName, testID, testHPR, testHW);

//Get the data from the employee and display it

System.out.println();
System.out.println("Employee Name: " + data.getName());
System.out.println("Employee ID Number: " + data.getIdNumber());
System.out.println("Employee Pay Rate: " + data.getPayRate());
System.out.println("Employee Hours worked: " + data.getHoursWorked());

}
}

In the lines you highlighted, you're assigning your class members to variables that don't exist.
