Question

Write a program that demonstrates the class by creating a Payroll object, then asking the user to enter the data for an employee.

Answer 1

Answer:

import java.util.Scanner;

public class Payroll {

   //set variable field

   private String name;

   private int idNumber;

   private double hourlyRate;

   private int hoursWorked;

   private double grossPay;

   //methods to get values of private class variables

   public String getName()

    {

        return name;

    }

   public int getIdNumber()

   {

      return idNumber;

   }

   public double getHourlyRate()

   {

       return hourlyRate;

   }

   public int getHoursWorked()

   {

       return hoursWorked;

   }

   public double getGrossPay()

   {

      return hoursWorked * hourlyRate;

   }

   //methods to initialize or change the private class values.

   public void setName( String nameGiven)

   {

       name = nameGiven;

   }

   public void setIdNumber(int idNumberGiven)

   {

       idNumber = idNumberGiven;

   }

   public void setHourlyRate(double rateGiven)

   {

       hourlyRate = rateGiven;

   }

   public void setHoursWorked(int hoursGiven)

   {

      hoursWorked = hoursGiven;

   }

   //Constructors

   public Payroll(String nameGiven, int idNumberGiven, double rateGiven, int hoursGiven)

   {

       name = nameGiven;

       idNumber = idNumberGiven;

       hourlyRate = rateGiven;

        hoursWorked = hoursGiven;

   }

 

   public static void main(String[] args)

   {

       double userGrossPay;

       String userEmplName;

       int userIdNum;

       double userRate;

       int userHours;

       Scanner scanner = new Scanner(System.in);

       System.out.print("Enter employee's name:");

       userEmplName = scanner.nextLine();

      System.out.print("Enter employee's ID number:");

       userIdNum = scanner.nextInt();

       System.out.print("Enter hourly rate:");

       userRate = scanner.nextDouble();

       System.out.print("Enter number of hours worked:");

       userHours = scanner.nextInt();

        Payroll payroll1 = new Payroll(userEmplName, userIdNum, userRate, userHours);

 

      payroll1.setName(userEmplName);

       payroll1.setIdNumber(userIdNum);

       payroll1.setHourlyRate(userRate);

       payroll1.setHoursWorked(userHours);

 

       System.out.printf(userEmplName + ", employee number " + userIdNum + ", made $%.2f in gross pay.\n", payroll1.getGrossPay());

}

}

Explanation:

The class "Payroll" is used to hold data of employees to be paid. the main function creates an instance of the class "payroll1", sets the name, id-number, hourly rate, and hours worked by the employee, then prints on screen the details of the payroll1 object.
