Employee payroll program problems

I have done good so far but now im stuck and lost on how to take my program to the next step, kids got sick and i missed like a week of school so im behind. I am suppose 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. I am lost on the bold part..
here is what I have:
//Calculates weekly pay for an employee
import java.util.Scanner; // program uses class Scanner
     public class BeemansPayroll
     private double rate;
     private double hours;
     private String name;
     //Used to save info
public BeemansPayroll(String Name, double PayRate, double Hours)
     String name = Name;
     double rate = PayRate;
     double hours = Hours;
private static void Quit()
System.out.println("Thank You for using Beeman's Payroll");
System.exit(0);
// main method begins execution of Java application
public static void main(String args[])
// create Scanner to obtain input from command window
Scanner input = new Scanner(System.in);
String name = "";
do {
System.out.print("Enter Employee Name or stop to quit: ");
// prompt for name
name = input.next(); // get name
          if (name.equals("stop"))
System.out.println("Thank You for using Beeman's Payroll");
Quit();
} //end if
else
double PayRate;
double Hours;
double Pay;
     System.out.print("Please enter Employee payrate:$ "); // prompt
     PayRate = input.nextDouble(); // read first number from user
          while (PayRate <= 0)
                    System.out.println ("Invalid amount, Payrate must be positive");
                    System.out.print("Please enter valid payrate:$ ");
                    PayRate = input.nextDouble();
               } //end if      
System.out.print("Please enter Employee hours: "); // prompt
Hours = input.nextDouble(); // read second number from user
                         while (Hours <= 0)
                    System.out.println ("Invalid amount, Hours must be positive");
                    System.out.print("Please enter hours worked: ");
                    Hours = input.nextDouble();
               } //end if
Pay = PayRate * Hours; // multiply numbers
System.out.printf("Employee Pay for the week %s, is $%.2f\n", name,
(PayRate * Hours)); // display product
} //end else
}while (!name.equals("stop"));
Quit();
} // end method main
} // end class Beeman's Payroll

Like I said, I am lost, with all that is going on I have done the reading 4 times , Then try reading a different source such as the Sun Java tutorials. They are excellent and there is no substitute to your reading and learning. We can help you debug an error in your code, but we are not a tutorial service nor a homework production service. Note also that we are all volunteers.
on top of kids getting sick and taking three algebra all at once. I advice you to not go on and on about this. This is not our problem and won't affect how or if someone helps you. If anything continued mention of this will turn many away who would otherwise help you.
How or where do I go about breaking it down?You are redeclaring the variables in your constructor, i.e.,:
String name = Name;  // don't do thisDon't do this because you'll never change the class's name variable this way. Instead in the constructor do something like this for each variable:
name = Name;or
this.name = Name;Later you will need to read up on Java naming conventions.
As for creating the method, you should read up on method creation in your text book or tutorial. That'll give you a better explanation than we can, I think.

    The problem I am having is getting the constructor to work with the rest of the program can someone please point out to me how to correct this. I have read my textbook as well as tutorials but I just don't seem to get it right. Please help.
    P.S. I have never taken a programming class before so please be kind.

  • Payroll Program Part 3 (confused)

    Okay, I'm sure you guys are sick of me by now. :-)
    This is the last part of an assignment that's supposed to calculate an employee's weekly pay, these are the requirements for this phase:
    Payroll Program Part 3:
    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.
    So I wrote the separate class:
    // Employee class stores and retrieves employee information
    import java.util.Scanner; // program uses class scanner
    public class Employee1
       // instance fields
       private double rate;
       private double hours;
       private String employeeName;
       // class constructor
       public Employee1()
          rate = 0.0;
          hours = 0.0;
          employeeName = "";
       } // end class Employee1 constructor
       // set rate
       public void setrate(double rate)
          rate = rate;
       } // end method setrate
       // get rate
       public double getrate()
          return rate;
       } // end method getrate
       // set hours
       public void sethours(double hours)
          hours = hours;
       } // end method sethours
       // get hours
       public double gethours()
          return hours;
       } // end method gethours
       // set employee name
       public void setemployeeName(String employeeName)
          employeeName = employeeName;
       } // end method setemployeeName
       // get employee name
       public String getemployeeName()
          return employeeName;
       } // end method getemployeeName
       // calculate and return weekly pay
       public double calculateWeeklyPay()
          return rate * hours; // display multiplied value of rate and hours
       } // end method calculateWeeklyPay
    } // end class Employee1...and modified the original program:
    // Payroll Program Part 3
    // Employee1 object used in an application
    import java.util.Scanner; // program uses class Scanner
    public class Payroll3
       // main method begins execution of Java application
       public static void main( String args[] )
          // create and initialize an Employee1 object     
          Employee1 employee = new Employee1(); // invokes Employee1 constructor
          employee.setrate();
          employee.sethours();
          Double weeklyPay = employee.calculateWeeklyPay();
          // create Scanner to obtain input from command window
          Scanner input = new Scanner( System.in );
          String employeeName = ""; // employee name to display
          Double rate; // first number to multiply
          Double hours; // second number to multiply
          Double weeklyPay; // product of rate and hours
          // loop until 'stop' read from user
          while( employeeName.equals("stop") )
             System.out.print( "Enter employee name or 'stop' to quit: "); // prompt
             employeeName = input.next (); // read employee name from user
             System.out.print( "Enter hourly rate: " ); // prompt
             rate = input.nextDouble(); // read first number from user
             // check if hourly rate is positive number
             if( rate <= 0 )
                System.out.print( "Enter a positive amount" );
                System.out.print( "Enter hourly rate: " ); // prompt
                rate = input.nextDouble(); // read first number from user
             } // end if
             System.out.print( "Enter hours worked: " ); // prompt
             hours = input.nextDouble(); // read second number from user
             // check if hours worked is positive number
             if( hours <= 0 )
                System.out.print( "Enter a positive amount" );
                System.out.print( "Enter hours worked: " ); // prompt
                hours = input.nextDouble(); // read second number from user
             } // end if
             weeklyPay = rate * hours; // multiply numbers
             System.out.printf( "Employee \n", employeeName); // display employee name
             System.out.printf( "Weekly pay is $%d\n", weeklyPay ); // display weekly pay
          } // end while
       } // end method main
    } // end class Payroll3I managed to compile the separate class just fine, but when I tried to compile Payroll3 I got these [three error messages|http://img150.imageshack.us/img150/3919/commandpromptrl9.jpg].
    I think I have an idea of what I did wrong, but I'm not sure what to change. I tried to emulate the code from some examples in my chapters and online but I'm a little in the dark about how these to files are actually supposed to work together.
    Also, the requirements say the program should end when 'stop' is entered as the employee name, I don't know if that applies to what I already have in Payroll3 or if I should use a sentinel controlled loop again in Employee1. I tried that and I got a whole host of error messages (probably did it wrong) so I just removed it.
    I'm going to play around with this a little more, I'm reluctant to change anything in my separate class since I managed to compile it, so I'm going to try some different things with Payroll3.
    If anyone has any suggestions I would greatly appreciate it, I'm a total newbie here so don't hesitate to state the obvious, it might not be so obvious to me (sorry for the lengthy post).

    employee.setrate();
    employee.sethours();First of all, your Employee1 class' setrate() and sethours() method both requires a parameter of type double.
    // loop until 'stop' read from user
    while( employeeName.equals("stop") )
    System.out.print( "Enter employee name or 'stop' to quit: "); // prompt
    employeeName = input.next (); // read employee name from userIf you want the while loop to stop when "stop" is entered, then change the condition to:
    while (!(employeeName.equals("stop))){code}
    This way the loop will perform whatever you tell it to do when it's NOT "stop".
    Also, take the prompt statements and paste them once outside the while loop, and a second time at the end of the loop:
    <example>
    == prompt for reply
    == while()
    == {
    == ....
    == prompt again

  • Payroll Program - please help

    I have a Java assignment due this Sunday, and I'm lost. I'm completely new to Java and this is only the second thing I've tried so far, so bear with me please, and don't laugh. :)
    This is the assignment:
    +"Create a non-GUI based Java application that calculates weekly pay for an+
    +employee. The application should display text that requests the user input the name+
    +of the employee, the hourly rate, and the number of hours worked for that week. The+
    +application should then print out the name of the employee and the weekly pay+
    +amount. In the printout, display the dollar symbol ($) to the left of the weekly pay+
    +amount and format the weekly pay amount to display currency."+
    In my chapter it talks about how to write a program that adds integers, so I tried to emulate that example but instead make it multiply. I wasn't sure how to do the employee's name, there is an explanation on printing lines of text, but not inputing and displaying text, only numbers. So for the employee's name I did some guesswork (for the data type declaration, etc), so I have no idea if that's right, (or if any of this is for that matter). I also don't know how to make it display the dollar symbol.
    Here is what I did so far:
    // Payroll Program Part 1
    import java.util.Scanner; // program uses class Scanner
    public class Multiplication
       // main method begins execution of Java application
       public static void main( String args[] )
          // create Scanner to obtain input from command window
          Scanner input = new Scanner( System.in );
          String name; // employee name to display
          int number1; // first number to multiply
          int number2; // second number to multiply
          int product; // product of number1 and number2
          System.out.print( "Enter employee name: "); // prompt
          name = input.nextString (); // read employee name from user
          System.out.print( "Enter hourly rate: " ); // prompt
          number1 = input.nextInt(); // read first number from user
          System.out.print( "Enter hours worked: " ); // prompt
          number2 = input.nextInt(); // read second number from user
          product = number1 * number2; // multiply numbers
          System.out.println( "Employee \n", name): // display employee name
          System.out.printf( "Weekly pay is %d\n", product ); // display product
       } // end method main
    } // end class MultiplicationKnow that I'm not asking anyone to do my homework for me, I just need some direction. I don't know what I'm doing, my teacher isn't helping and I'm not getting anything out of my chapters. Any assistance would be appreciated.

    You don't know how to print the $ symbol? Your code shows that you know how to print with System.out.println()...all that's left is finding the $ symbol on the keyboard...
    So what exactly is your problem? You say you don't know if your code is right. I have a suggestion...*run* your code and see if it works. If it works, it's right. If not, then come back here and let us know what it does do, including any exact error messages you might get.It's not easy to detect sarcasm over the Internet. Seriously I didn't think it would be that simple, but I just added the symbol, so now it says +"Weekly pay is $%d\n"+
    I don't know if that's in there right.
    Also, I tried to compile the program, and it found four errors, I fixed a couple (changed : to ; and apparently the public class name has to be the same as the file name, so now its public class Payroll1), but there are two others mistakes I made, both of which were my attempt at trying to include the program request the input and display the output for the employee name.
    They are both "cannot find symbol" errors, the first one is input.*nextString ()*; and the second is System.out.*println*
    So my guess at replacing int with "String" was wrong, and println is wrong. I'm going to try something else.

  • I need to install version 22 - nothing higher until 27 is available as my payroll program will not run. How do I install version 22 and not the most recent ver

    I need to install version 22. This is under the guidance of my payroll provider. The program will not work until version 27 comes out. I do not need help solving the problem with the payroll program, I just want to install version 22 of Firefox.

    Firefox 27.0 is in Beta at moment until February 4 release.
    You would be better off trying to use wither the User Agent Switcher extension or ua-site-switch extension to try a fool this one site or to use the portable Firefox 22.0 just for this one site.

    You should not switch to using 22.0 only due to known potential vulnerabilities that is fixed in newer versions like the current Fx 26.0.
    The Portable Firefox is a self contained program as it will not interfere with your current Firefox 26.0 install. It can even be used completely on a usb flash drive. http://sourceforge.net/projects/portableapps/files/Mozilla%20Firefox%2C%20Portable%20Ed./Mozilla%20Firefox%2C%20Portable%20Edition%2022.0/ and pick your language.

  • Payroll program

    I have a question. I have to write a payroll program that calculates and prints the monthly paycheck for an employee with 6 deductions coming out, fed and state tax, social, medicare/aid, pension and health.
    I need to structure it so it prompts the user to enter their gross pay amount and employee name, output stored in a file and output formatted to 2 places. I've tried finding other programs that would be similar to this so that I can use it as a guide to writing this one that I need to complete but I have not been able to find anything that gives me some solid help. Does anybody have a program I could look at to use as a guide for writing this or links that would show me how to proceed on structuring this. I'm lost at the moment and this is my last hope. Thanks for the guidance.

  • Payroll Program Assistance

    I need help with my payroll program which is for my Java class. The assignment is: 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 the class to calculate the weekly pay. Once stop is entered as the employee name, the application should terminate.
    With the program that I have below, I'm getting <indentier> expected
    weeklyPay.calculatePay( rate, hours );
    Help is needed as soon as possible because it is due today.
    import java.util.Scanner;
    public class Payroll3
    Employee weeklyPay = new Employee();
    weeklyPay.calculatePay( rate, hours );
    class Employee
    double rate;
    double hours;
    double pay;
    private String employeeName;
    public Employee( String name )
    employeeName = name;
    public void setEmployeeName( String name )
    employeeName = name;
    public String getEmployeeName()
    return employeeName;
    public static double calculatePay( double rate, double hours )
    Scanner input = new Scanner( System.in );
    System.out.print( "Enter employee name or stop to quit: " );
    employeeName = input.nextLine();
    while ( !employeeName.equals("stop") )
    System.out.printf( "Enter %s's hourly rate: ", employeeName );
    rate = input.nextDouble();
    System.out.printf( "Enter %s's number of hours worked: ", employeeName );
    hours = input.nextDouble();
    pay = rate*hours;
    System.out.printf( "%s's payment for the week is $%.2f\n", employeeName, pay );
    System.out.println();
    System.out.print( "Enter employee name or stop to quit: " );
    employeeName = input.next();
    System.out.println();
    }

    weeklyPay.calculatePay( rate, hours );What are rate and hours?
    Before you answer, no they are not available in your Payroll3 class becuase you declared them in the Employee class.

  • Java Programming Problem

    Hi all,
    I was looking for this java programming problem which had to do with a large building and there was some gallons of water involved in it too somehow and we had to figure out the height of the buiding using java. This problem is also in one of the java books and I really need to find out all details about this problem and the solution. NEED HELP!!
    Thanks
    mac

    Yes, it will. The water will drain from the bottom of
    the tank until the pressure from the water inside the
    tank equals the pressure from the pipe. In other
    words, without a pump, the water will drain out until
    there is the same amount of water in the tank as in
    the pipe The water pressure depends on the depth of the water, not the volume. So once the depth of the water inside the pipe reaches the same depth as the water inside the tank it will stop flowing. This will never be above the height of the tank.
    I found this applet which demonstrates our problem. If you run it you can drag the guy up to the top, when water in his hose reaches the level of the water in the tank it will stop flowing out.

  • Balancing BW Employee payroll to R3

    Hi,
    I'm looking for the best method to balance employee payroll (0PY_C02) between BW and R3.  We are using end-date of the in-period to allocate pay to month.  I'm trying to use the Wage Types report but it isn't evident how to select so as to get comparable data.  Is there a better method?

    For the record, this is possible using the Wage type report : Transaction PC00_M99_CWTR ou PGM H99CWTR0.
    You must make sure you use the in- or for-view, depending upon the option you take when assigning payroll data to calendar month (i.e. based in end date of in-period or for-period, etc)

    please help me urgently

    Hi yasser
    it's not precise for me , It needs a lot of details but according to the existing information
    Now we have 3 options
    Option1 : Get the transfer_fees according to AREA_CODE -- i don't know how not clear for me
    Option 2 : IF transfer_fees IS NULL then get it's value from up_area_code (then i am assuming that up_area_code has a value currently during the user input so all we have is to think that we can get it's value from a simple assign statement in WHEN-VALIDATE-ITEM trigger of transfer_fees item as ...
    IF :transfer_fees IS NULL THEN
    :transfer_fees  :=:up_area_code;
