Assignment 4:C# C# C#

Activities:

1. Rewrite the solution to assignment 3 with this new UML so to use polymorphism via interface according to the following UML class diagram to solve the payroll problem:

-------------------------------------------------------------------------------------------------

this is my code in as3:

using System;

namespace AsOPP {

//StaffMember: public abstract class StaffMember { // attributes protected string name; protected string address; protected string phone;

/// Constructor public StaffMember(string eName, string eAddress, string ePhone) { this.name = eName; this.address = eAddress; this.phone = ePhone; }

/// String representation of StaffMember public override string ToString() { return "Name: " + name + " Address: " + address + " Phone: " + phone; } // abstract method abstract public double Pay();

}

//Employee: public class Employee : StaffMember { // attributes protected string socialSecurityNumber; protected double payRate;

/// Constructor public Employee(string eName, string eAddress, string ePhone, string socSecNumber, double rate) : base(eName, eAddress, ePhone) { this.socialSecurityNumber = socSecNumber; this.payRate = rate; }

public override string ToString() { return base.ToString() + " Social Security Number: " + socialSecurityNumber + " Payrate: " + payRate; }

public override double Pay() { return payRate; }

}

//Volunteer:

public class Volunteer : StaffMember { /// Constructor public Volunteer(string eName, string eAddress, string ePhone) : base(eName, eAddress, ePhone) { }

public override string ToString() { return base.ToString(); }

public override double Pay() { return 0; } }

//Hourly: public class Hourly : Employee { // attribute private int hourlyWorked;

/// Constructor public Hourly(string eName, string eAddress, string ePhone, string socSecNumber, double rate) : base(eName, eAddress, ePhone, socSecNumber, rate) { hourlyWorked = 0; }

/// Adds moreHours to the hoursWorked public void addHours(int moreHours) { hourlyWorked += moreHours; }

public override string ToString() { return base.ToString(); } /// payrate public override double Pay() { return base.payRate * hourlyWorked; } }

//Executive: public class Executive : Employee { // attribute private double bonus;

/// Constructor public Executive(string eName, string eAddress, string ePhone, string socSecNumber, double rate) : base(eName, eAddress, ePhone, socSecNumber, rate) { bonus = 0; }

/// Award bonus public void awardBonus(double execBonus) { bonus = execBonus; }

/// Computes payRate public override double Pay() { return base.Pay() + bonus; } }

//Staff: public class Staff { // attributes private StaffMember[] staffList; private int totalStaff;

/// Constructor public Staff() { // get total number of Staffs Console.Write("Enter number of staffs: "); totalStaff = Convert.ToInt32(Console.ReadLine()); // declare the staffList to the user entered input staffList = new StaffMember[totalStaff]; // assign values to the list staffList[0] = new Executive("Sam", "123 Main Line", "555-0469", "123-45-6789", 2423.07); staffList[1] = new Employee("Salma", "456 Off Line", "555-0101", "987-65-4321", 1246.15); staffList[2] = new Hourly("Diane", "678 Fifth Ave.", "555-0690", "958-47-3625", 10.55); staffList[3] = new Volunteer("Khalid", "321 Dud Lane", "555-7282"); ((Executive)staffList[0]).awardBonus(500.00); ((Hourly)staffList[2]).addHours(40); }

public void payday() { // iterate till the list of staff for (int count = 0; count

//Firm: public class Firm { static void Main(string[] args) { // Create an instance of Staff Staff staff = new Staff(); Console.WriteLine(" Staff List"); // Print the details staff.payday(); } } }
