Help with constructors

Hello, I was asked to make these changes to my assignment:

Modify the Payroll 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

My problem is I am not sure if I am doing this correctly. I am writing this in Eclipse and the compiler runs everything in there so it seems the info is being passed between the classes fine, but my problem is when I try to compile in to .class in the command prompt window and run the main class (PayrollInfo) it tells me it cannot find or load the main class PayrollInfo.class

Am I just compiling this wrong? (I am compiling both classes before trying to run the main class) Or is my coding off?

Here is my code

PayrollInfo class

Code:

---

//PayrollInfo.java
//Eric Bowman 02/10/2013
//Program calculates weekly payroll for employees

import java.util.Scanner; //program uses scanner

public class PayrollInfo
{
        //main method begins program execution
        public static void main (String[] args)
        {
        //create scanner to obtain input from command window
        Scanner input = new Scanner (System.in);
       
        //defines the variables
        double hoursWorked;
        double hourlyPay;
        String empName;
       
        System.out.println("\nWelcome to the Payroll Program");
        System.out.println("This program will calculate weekly pay\n");
       
        while (true)
                {
                //prompt employee name input
                System.out.print("Enter employee's name or stop to quit: ");
                empName = input.nextLine();
                // breaks the loop if stop is entered
                if (empName.equalsIgnoreCase("stop"))
                {
                        break;
                }//terminates program
                //prompt hourly pay rate
                System.out.printf("What is %s's hourly pay rate: ", empName);
                hourlyPay = input.nextDouble();
                input.nextLine();
                //checks for positive number
                //allowed 0 as input in case employee still needs to be kept on record
                while (hourlyPay < 0)
                {
                        System.out.println("You must enter a positive number");
                        System.out.printf("What is %s's hourly pay rate: ", empName);
                        hourlyPay = input.nextDouble();
                        input.nextLine();
                }//end hourlyPay check       
                //prompt hours worked
                System.out.printf("How many hours did %s work: ", empName);
                hoursWorked = input.nextDouble();
                input.nextLine();
                //checks for positive number
                //allowed 0 as input in case employee still needs to be kept on record
                while (hoursWorked < 0)
                {
                        System.out.println("You must enter a positive number");
                        System.out.printf("How many hours did %s work: ", empName);
                        hoursWorked = input.nextDouble();
                        input.nextLine();
                }//end hoursWorked check
                //construct Employee class
                Employee employee = new Employee(empName, hoursWorked, hourlyPay );
                System.out.printf("%s's weekly pay is $%.2f%n%n",
                        employee.getName(), employee.getWeeklyPay());
                }//end while
        }//end main
}//end class PayrollInfo

Employee class:

Code:

---

public class Employee
{
        private String name;
        private double hours;
        private double hourlyPay;
        private double total;
       
        public Employee(String name, double hours, double rate)
        {
                this.setName(name);
                this.hours = hours;
                this.hourlyPay = rate;
                setWeeklyPay();
        }
       
        public double getWeeklyPay()
        {
                return total;
        }
       
        private void setWeeklyPay()
        {
                total = hours * hourlyPay;
        }
       
        public String getName()
        {
                return name;
        }

        public void setName(String name)
        {
                this.name = name;
        }
}

Can you copy the command prompt console's contents for when you run the javac and java commands and paste it here?

On windows: To copy the contents of the command prompt window:
Click on Icon in upper left corner
Select Edit
Select 'Select All' - The selection will show
Click in upper left again
Select Edit and click 'Copy'

Paste here.

I'm thinking that perhaps Employee shouldn't have a setWeeklyPay method or a total field. If it is supposed to have a getWeekleyPay() method, then the weekly pay should be calculated on the spot inside of the method when the method is called. I'm pretty certain that it should have getters and setters for hours and hourlyPay though.

You will need to show us exactly how you're trying to compile the code. You will want to copy the text from your cmd window and post it here so we can see exactly what you're trying to do. Is your code in any packages? Do you use the -cp . command on the command line?
