STEP 1: Understand the UML Diagram
Analyze and understand the object UML diagram, which models the structure of the program.
· There are no design changes to the Presentation Tier from the previous project and InputUtilities and ApplicationsUtilities classes are used without modification (except for changing the Application Information).
· The default values for each of the attributres have been declared as a constants, which is indicated by the ALL_CAPS in the name, and the attributes are then set using the default values
· Each of the attributes have been specified as private.
· The accessors (get) and mutators (set) are not shown on the class diagram, but it is ASSUMED that each private attribute has a corresponding property that contains the get and set methods.
· The "static" modifier for the numEmployees attribute means that there is only one copy of the variable that is then shared by all the objects of the class.
· There is a second CalculatePay method that overloads the existing CalculatePay method
· While not shown on the class diagram, the property for numEmployees will only have a get method, which means it will be a "read only" method. (A property with only and set method is a "write-only" property).

STEP 2: Create the Project
You will want to use the Week 2 project as the starting point for
the lab. To do this, you will want to create a new project by
following these steps:
1. Create a new project named
"CIS247_WK3_Lab_LASTNAME". An empty project will then
be created.
2. Delete the default Program.cs file that is created.
3. Click on Project->Add Existing Item…. Select the .cs files
containing the InputUtilities, ApplicationUtilities, Employee,
3. and Program classes from your project folder from last week's
lab.
4. The namespaces for the classes should all be "Employee", but
you should verify that the namespaces for all the classes are the
same.
5. Update the program information in the
ApplicationUtilities.DisplayApplicationInformation method to
reflect your name, current lab, and program description.
6. Build and execute the project.
For each week's assignments you will follow these steps create
a new project that reuses the program from the previous week.
STEP 3: Modify the Employee
Be sure you follow proper commenting and programming styles
(header, indentation, line spacing, etc.).
Using the Employee class diagram as a guide modify the
Employee class:
1. Add the constants to the class using the following as an
example:
public const double MIN_SALARY = 20000;
2. In the default constructor, update assignment statements to
use the defined constants
3. Change all the employee class attributes to private.
4. Create a private static numEmployees variable and initialize
it to zero
5. Increment numEmployees by 1 in each of the constructors
6. For each private attribute, create a well-named property that
contains the get and set methods. The get method of the
property only needs to return the value of the attribute; but the
set method of each property needs to validate the provided
value using the following validation rules:
a. If the provided first or last values are empty, or a null value,
then set the name to DEFAULT_NAME.
b. If the provided gender value is 'F', 'f', 'M', or 'm' set the
value; otherwise set the value to DEFAULT_GENDER.
c. If the provided dependent value is between the
4. MIN_DEPENDENTS and MAX_DEPENDENTS (inclusive) then
set dependent to the provided value; if the provided value is
less than MIN_DEPENDENTS set the dependents to
MIN_DEPENDENTS; else if provided value is greater than
MAX_DEPENDENTS set the dependents to
MAX_DEPENDENTS.
d. If the provided salary value is between the MIN_SALARY
and MAX_SALARY (inclusive) the set the annualSalary to the
provided value; if the provided value is less than
MIN_SALARY set the annualSalary to MIN_SALARY; else if
provided value is greater than MAX_SALARY set the
annualSalary to MAX_SALARY.
e. For the numEmployee attribute create a property called
NumberEmployees that only contains a "get" method, external
objects should NOT be allowed modify the numEmployee value.
Since numEmployees is a static method, the property must be
declared as static.
7. In the parameterized constructor, change statements that set
the attributes so that the properties are used, which ensures that
attributes are validated prior to be set.
8. Create the overloaded CalculateWeeklyPay method that
accepts a double "modifiedSalary" argument. The method shall
update the annualSalary attribute (use the AnnualSalary
property to ensure the value is valid), and then return the
updated weekly pay based on the new annual salary value.
STEP 4: Modify the Main Method
In the Main class, create code statements that perform the
following operations. Be sure you follow proper commenting
and programming styles (header, indentation, line spacing, etc.)
and use the ApplicationUtiltities methods to logically separate
the operations in the output.
To access a property of an object/class, you continue to use the
DOT notation; however, a property DOES NOT require the
parenthesis and you just use the assignment operator (=) to set
or get the value, which makes using propertys very easy. For
5. example to set the first name, the statement would look
something like:
employee1.FirstName = "John"
To get the full name, the statement would look look something
like:
theName = employee1.FirstName + " " + employee1.LastName
Notice, there is no use of parenethese, only the assignment
operator, when using properties.
The Main method code from the previous week's lab performed
the following operations, ensure that your project correctly
implements these operations before moving on the new
operations for this week.
1. Display the program information.
2. Create an Employee object using the default constructor.
3. Prompt for and then set the first name, last name, gender,
dependents, and annual salary. Remember to use the appropriate
methods in the InputUtilties class to prompt for and retreive the
values.
4. Display the employee information.
5. Create a second Employee object using the multi-argument
constructor using data of your choosing that is the correct type
and within the valid ranges for each of the attributes.
6. Display the Employee information for the second employee
object.
7. Terminate the application
Once your code is working and implements the previous week's
operations, modify the code to implement the following new
requirements (updated code should implement all previous
requirements except as noted below).
1. After the first employee information is provided, display the
number of employees created.
2. Prompt the user to provide an updated annual salary for
employee1, retrieve the value and invoke the overloaded
CalculateWeeklyPay, and then display only the updated weekly
pay.
3. Create a third Employee object using the parameterized
6. constructor setting each of the attributes with the following
values: "Sue", "Smith", 'F', 15, 500000.0
4. Display the employee information for the third Employee
object and verify that the dependents and annual salary values
have been set to the maximum values by the properties. If not,
make sure you change the parameterized constructor to use the
properties to set the attributes.
5. Display the number of employees created.
STEP 5: Compile and Test
When done, compile and execute your code. Debug errors until
your code is error-free. Check your output to ensure that you
have the desired output, modify your code as necessary, and
rebuild. The following shows some sample output, but your
output may look different.

STEP 2: Create the Project
You will want to use the Week 3 project as the starting point for
the lab. To do this, you will want to create a new project by
following these steps:
1. Create a new project named
"CIS247_WK4_Lab_LASTNAME". An empty project will then
be created.
2. Delete the default Program.cs file that is created.
3. Now that we are beginning to add more classes to our
projects the
Solution
Explorer can become difficult to organize so you will create
folders to hold the Presentation Tier and Logic Tier Files in
order to organize the project. One thing to remember, even
though we only have a few files in our project, a professional
program will have 100's if not 1000's of files in a project so you
will want to get practice in organizing your project files in a
logical folder heirarchy and we will use the Tiered Architecture
structure shown in the UML Class diagram for the folder
11. structure. You will find that creating folders within MS Visual
Studio is very similiar to creating folders in Windows Explorer.
Follow these directions to create the folders:
1. Select the project and then right click
2. Select Add
3. Select New Folder
4. Enter the name of the folder
4. Add the following three folders to your project (1)
Presentation Tier, (2) Logic Tier, and (3) Utilities.
5. You are going to add the files from the previous week lab to
the project just as you did before, but now you add the existing
files to the corresponding folder
6. Select the PresentationTier folder, right click and select Add
then Existing Item, navigate to your previous week's project and
select the InputUtitilies.cs and Program.cs files and click add.
These two files will then be added to the Presentation. [Hint:
you can also drag and drop the files directly from Windows
Explorer directly into the corresponding folder in your project!]
7. Add the previous week's Employee.cs file to the Logic Tier
folder. You will also add the new Benefits class to this folder.
8. Add the ApplicationUtilities.cs file to the Utilities folder.
9. Your solution explorer should look similiar to the following
(note: you can rename any folder by selecting the folder, right
click, and then Rename just like you do in Windows).
12. 10. The namespaces for the classes should all be "Employee",
but you should verify that the namespaces for all the classes are
the same.
11. Update the program information in the
ApplicationUtilities.DisplayApplicationInformation method to
reflect your name, current lab, and program description.
12. Build and execute the project.
STEP 3: Create the Benefits Class
Using the Benefit class diagram as a guide, build the Benefit
class by adding a new class to the Logic Tier folder.
1. Create a property for each of the listed private attributes and
validate the provided value using the following rules:
a. If the insurance company provided is empty or null then set
the healthInsuranceCompany to
DEFAULT_HEALTH_INSURANCE
b. If the provided life insurance value is between the
MIN_LIFE_INSURANCE and MAX_LIFE_INSURANCE
(inclusive) then set lifeInsuranceAmount to the provided value;
if the provided value is less than MIN_LIFE_INSURANCE set
the lifeInsuranceAmount to MIN_LIFE_INSURANCE; else if
provided value is greater than MAX_LIFE_INSURANCE; set
thelifeInsuranceAmount to MAX_LIFE_INSURANCE.
c. If the provided vacation days value is between the
MIN_VACATION and MAX_VACATION (inclusive) the set the
13. vacationDays to the provided value; if the provided value is less
than MIN_VACATION set the vacationDays to
MIN_VACATION; else if provided value is greater than
MAX_VACATION set the vacationDays value to
MAX_VACATION.
2. In the parameterized constructor, set the attributes so that the
properties are used, which ensures that attributes are validated
prior to be set.
3. Create an overridden ToString method that collects and
formats the attribute information for the benefit object. Ensure
to display life insurance amount in currency format.
STEP 4: Modify the Employee Class
Using the Employee class diagram as a guide, modify the
Employee class
1. Add a private attribute called "benefit" to the employee class
of type Benefits
2. Create a public Benefit property that returns the benefit
attribute. In the set method of the property, if the provided
value is null then re-instantiate the benefit variable; otherwise,
set the provided value to the benefit variable. [Hint: to check if
a object is null use the syntax "if (object != null)"]
3. In the default constructor, instantiate the benefit variable
using the Benefits default constructor
4. In the parameterized constructor, add a benefit argument of
14. type Benefits, and then set the value of this parameter to the
Benefit property (using the property will ensure that any null
benefit object is correctly instansiated.)
5. Modify the ToString method to the Employee class, by
adding a call to the Benefits ToString methods at the end of the
Employee ToString method.
STEP 5: Modify the Main Method
In the previous labs you learned how to access an object/class
methods and properties using the DOT notation. For example, to
access the calculatePay method of an employee object you used
a statement similiar to:
employee1.CalculateWeeklyPay(modifiedSalary)
Notice that the Employee class now has a public Benefit object
inside it. This means that you can access the set methods of the
Benefit object using the transitive notation:
containingObject.containedObject.methodName()
or
containingObject.containedObject.PropertyName
That is to access the members of contained object, you start at
the containing object, then "transit" to the contained object,
then to the contained objects members.
As an example, to set the life insurance amount of an employee
object, the statement would look something like:
employee1.Benefit.LifeInsuranceAmount = 100000;
Notice, the containing object is "employee1", the contained
15. object is "Benefit", and the property of Benefit we are accessing
is LifeInsuranceAmount.
The code in the previous week's project performed the following
operations
1. Display the program information.
2. Create an Employee object using the default constructor.
3. Prompt for and then set the first name, last name, gender,
dependents, and annual salary. Remember to use the appropriate
methods in the InputUtilties class to prompt for and retreive the
values.
4. Display the employee information.
5. After the first employee information is provided, display the
number of employees created.
6. Prompt the user to provide an updated annual salary for
employee1, retrieve the value and invoke the overloaded
CalculateWeeklyPay, and then display only the updated weekly
pay.
7. Create a second Employee object using the multi-argument
constructor using data of your choosing that is of the correct
type for each input.
8. Display the Employee information for the second employee
object.
9. Create a third Employee object using the parameterized
constructor setting each of the attributes with the following
values: "Sue", "Smith", 'F', 15, 500000.0
16. 10. Display the employee information for the third Employee
object and verify that the dependents and annual salary values
have been set to the maximum values by the properties. If not,
make sure you change the parameterized constructor to use the
properties to set the attributes.
11. Display the number of employees created.
12. Terminate the application
Once your code is working and implements the previous week's
operations, modify the code to implement the following new
requirements (updated code should implement all previous
requirements except as noted below).
1. After you collect the information for the first employee
object, prompt for and collect the Health Insurance Company,
the LifeInsuranceAmount, and the number of vacation days.
2. Display the updated employee 1 information
3. Display the number of employees created.
4. Create a new, standalone benefits object using the multi-
argument constructor using data of your choosing that is of the
correct type for each input.
5. Modify the second employee object instantiation and add the
newly created benefit object to the constructor call.
6. Display the updated employee 2 information
7. Display the number of employees created.
8. Create a new, standalone benefits object using the multi-
argument constructor using the following invalid data "" (empty
17. string), 10000000, -10
9. Modify the third employee object instantiation and add the
newly created benefit object to the constructor call.
10. Display the updated employee 3 information and verify that
the default values for the benefit object have been correctly set.
11. Display the number of employees created.
STEP 6: Compile and Test
When done, compile and execute your code. Debug errors until
your code is error-free. Check your output to ensure that you
have the desired output, modify your code as necessary, and

has possible values from MIN_MANAGEMENT_LEVEL to
MAX_MANAGEMENT_LEVEL and a BONUS_PERCENT.
· The Salaried class has a default constructor and parameterized
constructor that accepts all the general employee information
20. plus the management level.
· The Hourly has a wage attribute, which respresents the hourly
wage that ranges from MIN_WAGE to MAX_WAGE, a hours
attributes, which represents the number of hours worked in a
week that ranges from MIN_HOURS to MAX_Hours, and a
category attributes that accepts string values.
· The Hourly class has a default constructor and parameterized
constructor that accepts all the general employee information
plus the hours and wage value.
· The Presentation Tier contains two new classes (1) The
EmployeeInput class and the EmployeeOutput class
· The EmployeeInput class contains three static methods (1)
CollectEmployeeInformation, which accepts any type of
Employee object as a argument; (2) CollectHourlyInformation,
which accepts only Hourly objects as an argument, and (3)
CollectSalariedInformation, which accepts only Salaried objects
as an argument.

Presentation Tier Description
The image of the presentation tier depicts 5 classes, the
Program Class, ApplicationUtilities, InputUtilities,
21. EmployeeInput, and EmployeeOutput. Only the EmployeeInput
and EmployeeOutput classes are describe here. Both utility
classes are the same as they were since given in Week 2.
Program changes based on lab specification, not formal
definition other than the Main method is specified.
EmployeeInput Class Diagram Description
What is depicted is a single column table with 3 rows. In the
first row is the large word "EmployeeInput".
The second row is blank. In essence there are no constructors
since the methods in this class are all static.
In the third and final row beneath this is a list of public
methods, indicated with a "plus" symbol before them (but no
space after). As stated previously, all these methods are static.
These are:
+CollectEmployeeInformation(in theEmployee : Employee)
+CollectHourlyInformation(in theEmployee : Hourly)
+CollectSalariedInformation(in theEmployee : Salaried)
Lastly, there is a line between the Program class and
EmployeeInput class indicating the uses relationship. The
Program class uses the static methods from EmployeeInput.
EmployeeOutput Class Diagram Description
What is depicted is a single column table with 3 rows. In the
first row is the large word "EmployeeOutput".
The second row is blank. In essence there are no constructors
since the methods in this class are all static.
22. In the third and final row beneath this is a list of public

STEP 2: Create the Project
You will want to use the Week 4 project as the starting point for
27. the lab. Use the directions from the previous weeks labs to
create the project and the folders.
1. Create a new project named
"CIS247_WK4_Lab_LASTNAME". An empty project will then
be created.
2. Delete the default Program.cs file that is created.
3. Add the Logic Tier, Presentation Tier, and Utilities folders to
your proejct
4. Add the Week 4 project files to the appropraties folders.
5. Update the program information in the
ApplicationUtilities.DisplayApplicationInformation method to
reflect your name, current lab, and program description
Note: as an alternative you can open up the Week 4 project and
make modifications to the existing project. Remember, there is
a copy of your project in the zip file you submitted for grading.
Before attempting this week's steps ensure that the Week 4
project is error free.
STEP 3: Modify the Employee Class
1. Change the access specifier for all the private attributes to
protected.
2. Add the new attribute employeeType, along with a "read
only" property (that is only a "get" method) to access the
employee type value.
3. Add a new constructor that only accepts the type attribute,
which is then used to set the employeeType value. Also, this
28. constructor should initialize all the default values. You can call
the default constructor using the syntax: public Employee(string
employeeType) : this() {}
4. Modify the parameterized constructor that accepts the
employee information to accept the employee type, and then set
the employeeType with this value.
5. Modify the ToString Method to include the employee type.
STEP 4: Create the Salaried Class
1. Using the UML Diagrams, create the Salaried class, ensuring
to specify that the Salary class inherits from the Employee
class.
2. For each of the constructors listed in the Salaried class
ensure to invoke the appropriate super class constructor and
pass the correct arguments to the super class constructor.
3. Override the CalculateWeeklyPay method to add a 10 percent
bonus to the annualSalary depending on the management level.
The bonus percent is a fixed 10 percent, and should be
implemented as a constant. However, depending on the
management level the actual bonus percentage fluctuates (i.e.,
actualBonusPercentage = managementLevel *
BONUS_PERCENT).
4. Override the ToString method to add the management level to
the employee information.
STEP 5: Create the Hourly Class
1. Using the UML Diagrams, create the Hourly classes, ensuring
29. to specify that the Hourly class inherits from the Employee
class.
2. For each of the constructors listed in the Hourly class ensure
to invoke the appropriate super class constructor and pass the
correct arguments to the super class constructor. Notice, that the
Hourly employee DOES NOT have an annual salary, which we
will then have to calculate (see below).
3. Create a Category property (get/set) and the valid category
types are "temporary", "part time", "full time".
4. Create a Hours property (get/set) for the hours attributes and
validate the input using the constants shown in the UML
diagram, but since an Hourly employee does not have a formal
annual salary we will need to calculate this each time the hour
(and wage) properties are set. Add the following code after the
validation code in the hours property: base.AnnualSalary =
CalculateWeeklyPay() * 48; (assumes working 48 weeks a
year).
5. Create an Wage property (get/set) for the wage attributes and
validate the input using the constants shown in the UML
diagram. Add the following code after the validation code in the
wage property: base.AnnualSalary = CalculateWeeklyPay() *
48; (assumes working 48 weeks a year)
6. Override the CalculateWeeklyPay method by multiplying the
wages by the number of hours.
7. Update the ToString method to add the category, hours, and
30. wages to the hourly employee information.
STEP 6: Create the EmployeeInput Class
1. Create a new class in the Presentation Tier folder called
"EmployeeInput"
2. Create a static void method called
CollectEmployeeInformation that has a single Employee
parameter. The declaration should look something like the
following:
public static void CollectEmployeeInformation(Employee
theEmployee)
3. Write code statements similiar to what you created in the
Week 4 project to collect the generic employee information
from the user, except instead of using specific employee objects
use the "theEmployee" parameters. For example:
In Week 4, you had something like:
employee1.FirstName =
InputUtilities.GetStringInputValue("First name");
In the CollectionEmployeeInformation method this can be
translated to the following;
theEmployee.FirstName =
InputUtilities.GetStringInputValue("First name");
31. 4. Write statements to collect all the generic employee
information, including the Benefits information, as you did in
the Week 4 project. However, since not all derived types have a
AnnualSalary value, DO NOT collect the annual salary data.
5. Create a new static void method called
CollectEmployeeInformation that accepts an Hourly employee
object. Using the InputUtilities methods write statements to
collect the wage and hours from the user.
6. Create a new static void method called
CollectSalariedInformation that accepts a Salaried employee
object. Using the InputUtilties methods write statements to
collect the management level and the annual salary.
STEP 7: Create the EmployeeOutputClass
1. Create a new class in the Presentation Tier folder called
"EmployeeOuput"
2. Create a static void method called
DisplayEmployeeInformation that has a single Employee
parameter. The declaration should look something like the
following:
public static void DisplayEmployeeInformation(Employee
theEmployee)
3. In the DisplayEmployeeInformation method write an output
statement that displays theEmployee object to string method to
the console.
32. 4. Create static method called DisplayNumberObject that
displays the number of employees created.
5. Invoke these methods from the main program to display the
employee information and number of objects created.
[Hint: move the the statements from the main program into
these methods.]
STEP 8: Create the Main Program
1. Create an array of type Employee that will hold three
employee objects. Create three new objects, one Employee, one
Hourly and one Salaried in positions 0, 1 and 2 of the array
respectively. Make sure to use the constructors the accept the
employee type and provide appropriate values for the employee
type (e.g. "Generic", "Hourly", "Salaried").
2. Using a FOR loop iterate through the array and collect all the
generic employee information, using the
EmployeeInput.CollectEmployeeInformation method.
3. If the current item in the array is an Hourly object, then use
the EmployeeInput.CollectHourlyInformation method to collect
the hourly information.
4. If the current item in the array is a Salaried object, then use
the EmployeeInput.CollectSalariedInformation method to
collect the salaried information.
Use the following if statement to determine the specific type of
object:
33. if (employeeList[i] is Hourly)
EmployeeInput.CollectHourlyInformation((Hourly)employeeLis
t[i]);else if (employeeList[i] is Salaried)
EmployeeInput.CollectSalariedInformation((Salaried)employee
List[i]);
5. After the information has been collected display the
employee information using the
EmployeeOutput.DisplayEmployeeInformation method.
6. Before terminating the program display the number of
employee objects that have been created.
STEP 9: Compile and Test
When done, compile and run your program.
Then debug any errors until your code is error-free.
Check your output to ensure that you have the desired output
and modify your code as necessary and rebuild.
The output of your program should resemble the following:
34. total Number of Employess in Database: 3

STEP 10: Submit Deliverables
· Capture the console output window and paste into a Word
document.
· Put the zip file and screen shots (Word document)
6/6.docx
STEP 1: Understand the UML Diagram
Analyze and understand the object UML diagram, which models
the structure of the program.
· The Employee class has been specifed as abstract, which is
denoted by the name of the class being italized Employee
· The Employee class as a new method CalculateNetPay which
is an abstract method, denoted by the italized name of the
method. Since this method is an abstract method the
CalculateNetPay method WILL NOT have an implementation in
the Employee class.
· The Salaried and Hourly classes both have a new method
CalculateNetPay that is inherited from the abstract Employee
class and the Salaried and Hourly class both MUST implement
35. the CalculateNetPay method.The image of the logic tier depicts
4 classes, the Employee Class, the Benefits Class, the Hourly
Class (derived from Employee), and Salaried Class (also,
derived from Employee).

STEP 2: Create the Project
You will want to use the Week 5 project as the starting point for
the lab. Use the directions from the previous weeks labs to
create the project and the folders.
1. Create a new project named
40. "CIS247_WK4_Lab_LASTNAME". An empty project will then
be created.
2. Delete the default Program.cs file that is created.
3. Add the Logic Tier, Presentation Tier, and Utilities folders to
your proejct
4. Add the Week 5 project files to the appropraties folders.
5. Update the program information in the
ApplicationUtilities.DisplayApplicationInformation method to
reflect your name, current lab, and program description.
Note: as an alternative you can open up the Week 5 project and
make modifications to the existing project. Remember, there is
a copy of your project in the zip file you submitted for grading.
Before attempting this week's steps ensure that the Week 5
project is error free.
STEP 3: Modify the Employee Class
1. Modify the class declaration of the Employee class to specify
that the Employee class is an abstract class
2. Declare an abstract method called CalculateNetPay that
returns a double value.
3. Modify the ToString Method to include the weekly net pay in
currency format.
STEP 4: Modify the Salaried Class
1. Add a double constant called TAX_RATE and set the value to
.73
2. Implement the CalculateNetPay method by multiplying the
41. weekly pay by the tax rate.
STEP 5: Modify the Hourly Class
1. Add a double constant called TAX_RATE and set the value to
.82
2. Implement the CalculateNetPay method by multiplying the
weekly pay by the tax rate.
STEP 6: Create the Main Program
1. Change the employeeList array to only hold two objects
2. Create one Hourly employee object and store it in the array.
3. Create one Salaried employee object and store it in the array.
4. As you did in the Week 5 lab, prompt for and collect the
information for each of the objects.
Note: iterating through the array should not require any changes
from the previous iteration of the project--but make sure that
the loop stays within the bounds of the array.
STEP 7: Compile and Test
When done, compile and run your program.
Then debug any errors until your code is error-free.
Check your output to ensure that you have the desired output
and modify your code as necessary and rebuild.
The output of your program should resemble the following:
