Can Someone Help Me?

[booter4429]

Hello all,

I'm new to Java and need some help. I am trying to 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. Once
stop is entered as the employee name, the application should terminate. Make sure the
program maintains all the functionality required in previous assignments and your source
code is readable and well documented. Use feedback you have received from the
instructor to make any needed modifications.


This is what I have so far.

System.out.print("Number of Hours Worked:");
HoursWorked=input.nextDouble();

while (HoursWorked <= 0)

System.out.print("Hours Worked must have a positive value. Please reenter:");

HourlyRate = input.nextFloat();
}





Employee2 employee =
new Employee2(EmpName, HourlyRate , HoursWorked);

System.out.printf( "Employee Name: %s, Weekly pay is $%,.2f\n",
employee.empName, employee.getWeeklyPay() );

}


}

}
class Employee2
{
String empName;
double hoursWorked;
double payRate;
double Total;

public Employee2(String name, double HoursWorked, double HourlyRate)
{
this.empName = name;
this.hoursWorked = HoursWorked;
this.payRate = HourlyRate;
computeWeeklyPay();
}

private void computeWeeklyPay()
{
Total = hoursWorked * payRate;
}

public double getWeeklyPay()
{
return Total;

}
}

in between where is says input next Double and print HoursWorked = next double is where you need to do some calculations. The way we do that would be

float anAmount = HourlyRate.toFloat();

That just gets you a value that you can add, subtract, multiply and divide. Did your instructor show you how to do that? Is this a classroom instructed course? Have you read any basic Java books or know how to write the simplest Java program? This is not a complex program but looks like that if you have never seen Java before.

What do you need help on?
Compiler errors?
Runtime errors?
Wrong output? - Please show what you get and how you want it changed.

It Just not working the way I think it need too.?? I can't get it to retrieve name or anything else.??

I have no idea what I'm doing wrong....

You'll have to explain. Copy the output and add comments to it to show how you think it should work.
Where is it trying to retrieve name? Add comments to the code at the point something like: // NOT getting name here

Code:

import java.util.Scanner;

public class W4Rx
{
    public static void main(String[] args)
    {
        Scanner input = new Scanner(System.in);
        boolean stop = false;

        while (!stop)
        {
            double HourlyRate=0.0;
            double HoursWorked=0.0;

            System.out.print("Employee Name or stop to end program:");
            String EmpName = input.nextLine();

            if (EmpName.equals("stop")) 
            {
                System.out.println( "Program End." );

                stop = true;
            }
            else
            {
                System.out.print("Number of Hours Worked:");
                HoursWorked = Double.parseDouble(input.nextLine());

                while (HoursWorked <= 0)
                {
                    System.out.print("Hours Worked must have a " +
                                     "positive value. Please reenter:");

                    HoursWorked = Double.parseDouble(input.nextLine());
                }

                System.out.print("Hourly Pay Rate:");
                HourlyRate = Double.parseDouble(input.nextLine());

                while (HourlyRate <=0)
                {
                    System.out.print("Hourly rate must be a " +
                                     "positive value. Please reenter:");

                    HourlyRate = Double.parseDouble(input.nextLine()); 
                }

                Employee2 employee =
                    new Employee2(EmpName, HourlyRate , HoursWorked);

                System.out.printf( "Employee Name: %s, Weekly pay is $%,.2f\n",
                                    employee.empName, employee.getWeeklyPay() );
            }
        }
    }
}

But how do I retrieve data for the employee?

But how do I retrieve data for the employee?
The way you did here

Code:

System.out.printf( "Employee Name: %s, Weekly pay is $%,.2f\n",
                    employee.empName, employee.getWeeklyPay() );

by accessing fields and methods of the Employee2 class.

But if I run the application and input the name it doesn't retrieve anything.

Hardwired put some code up, did you study the code and see what he did and where? This may be too much code for you to navigate. If so, ask us. Probably you need to trace the flow of data from main( String[] args) to where you use it and see how he did it compared to how you did it.

He used a Scanner, you probably have not put that in your code yet.

[booter4429]

HoursWorked = Double.parseDouble(input.nextLine());

HourlyRate = Double.parseDouble(input.nextLine());

This is the only thing that is new. And if I use that I still can't get it to retrieve.??

And yes I have used a Scanner but I think I'm lost. LOL

This is going to be a fun night.
