Create a new project named "CIS247_WK4_Lab_LASTNAME" based on the Week 3 project. Organize the project by creating folders for the Presentation Tier, Logic Tier, and Utilities. Add existing files from the previous week into the appropriate folders. Update namespace to "Employee" and modify ApplicationUtilities.DisplayApplicationInformation with your details. Build and run the project to ensure proper setup.

The purpose of this assignment is to develop a well-organized, tiered C# project that encapsulates employee benefit information and demonstrates object-oriented programming principles. Starting from a previous week's project, it emphasizes structured folder organization, class design, property validation, and layered architecture implementation to reflect professional coding standards.

First, the project setup involves creating a new Visual Studio solution titled "CIS247_WK4_Lab_LASTNAME." The process begins with deleting default files, especially "Program.cs," to allow for custom application structure. To promote maintainability and scalability, the project should be organized into three primary folders: Presentation Tier, Logic Tier, and Utilities. These folders help compartmentalize the code according to the tiered architecture pattern shown in the UML class diagram, simulating best practices used in large-scale enterprise applications.

File management is essential. Files from the previous week, specifically "InputUtilities.cs" and "Program.cs," are to be added to the Presentation Tier folder, either through right-clicking and selecting "Add Existing Item" or simply dragging from Windows Explorer. Likewise, "Employee.cs" and the new "Benefits" class belong in the Logic Tier, whereas "ApplicationUtilities.cs" fits within the Utilities folder. Ensuring that all classes share the same namespace, "Employee," maintains consistency and simplifies referencing across the project.

Modifying the "ApplicationUtilities" class, particularly the method "DisplayApplicationInformation," should include personal details and project specifics to make the program output meaningful. After these setup steps, build the project to confirm successful compilation and execution.

Next, the core of this assignment involves creating the "Benefits" class, guided by the class diagram. This class requires properties for health insurance company, life insurance amount, and vacation days, each with validation rules:

  • The insurance company string cannot be null or empty; if it is, assign a default value like "DEFAULT_HEALTH_INSURANCE."
  • The life insurance amount must be within a specified range, bounded by "MIN_LIFE_INSURANCE" and "MAX_LIFE_INSURANCE."
  • The vacation days must be between "MIN_VACATION" and "MAX_VACATION."

The class constructor should assign initial values through properties, ensuring validation logic is enforced. Additionally, override the "ToString" method to produce a formatted string detailing all attributes, especially formatting the insurance amount as currency for clarity.

Following this, the "Employee" class needs modification to include a private "benefit" attribute of type Benefits, with a public property to access and modify it. The property setter must instantiate a new Benefits object if the input is null, preventing null reference issues. The default constructor should initialize "benefit" with its default constructor, while the parameterized constructor should accept a Benefits object and assign it via the property to utilize validation logic.

The "ToString" method in "Employee" must be updated to include the benefits information by invoking the "Benefits" class's "ToString" method, providing a comprehensive view of employee data with benefits details.

The "Main" method plays a significant role in demonstrating class interactions. With the benefits property added, accessing and setting benefit attributes now involves transitive notation, for example:

employee1.Benefit.LifeInsuranceAmount = 100000;

This transitive approach aligns with object-oriented design, encapsulating benefit details within the employee object.

In this step, the program workflow involves displaying program info, creating Employee objects (using default, multi-argument, and parameterized constructors), prompting for user input via "InputUtilities," and displaying employee information. The code must handle maximum value constraints, such as ensuring dependents and salary do not exceed defined maximums, by utilizing properties that enforce validation.

Subsequently, after initial employee creation, the user is prompted to provide additional benefit information for the first employee, including the health insurance company, benefit amount, and vacation days. This data then updates the employee's benefits, triggering validation and default value assignment if necessary. The program is also required to construct standalone Benefits objects with specific and intentionally invalid data (e.g., an empty string or negative values) to test the validation logic, and assign them to new Employee instances, verifying that default settings are correctly enforced.

The final steps involve compiling, debugging, and testing the complete application, ensuring all features work correctly. Output should be captured and pasted into a Word document, and both the code and screenshots to document the process are to be submitted.
