Create An Employee Class With The Following Propertiesfirst Namelast

This paper details the development of an object-oriented application designed to manage employee records, illustrating inheritance, file processing, and user interaction within a desktop or web environment. The system defines a base class for employees and subclasses for managers and developers, which incorporate additional attributes pertinent to each role. Data is loaded from a user-selected text or CSV file, parsed into objects, and dynamically displayed based on user input, demonstrating core programming principles and user interface design.

Introduction

In contemporary software development, organizing data efficiently and extending functionality through object-oriented programming (OOP) principles are fundamental. This project exemplifies such principles by creating a class hierarchy to model employees, with specific subclasses for managers and developers. Additionally, it incorporates file input operations and dynamic display capabilities, which are critical for real-world enterprise applications that manage large datasets and require user-driven data exploration.

Design of Employee Classes and Inheritance

The core of the system involves establishing a base class called Employee, which encapsulates common properties such as First Name, Last Name, Street Address, City, State, and Zip. Subclasses Manager and Developer extend Employee, adding role-specific attributes. This inheritance structure promotes code reuse and logical organization, aligning with best practices in OOP.

Employee Class

The Employee class acts as a blueprint for all employee objects. It stores personal and contact information and serves as the parent for specialized employee roles. This class provides methods for initializing data, accessing properties, and possibly updating records in a real-world application.

Manager Subclass

The Manager class extends Employee by adding Cost Center and Supervisor properties. These fields are pivotal for managerial responsibilities and organizational structure, enabling role-specific operations and reporting.

Developer Subclass

The Developer subclass enhances Employee with Developer Type (such as Script, .NET, Mobile), Supervisor, and Tax Type (W2, 1099-Contract). These additional attributes facilitate payroll, project management, and compliance tracking.

File Input and Data Parsing

The application provides a user interface element, such as a file selector, to load employee data from a text or CSV file. Each file line represents a single employee, structured as comma-separated values in the specified format. Upon file selection, the program reads each line, splits the data into fields, and instantiates the appropriate subclass objects based on the Employee Type. Data validation ensures integrity, and exception handling accounts for malformed lines or unexpected data.

Loading and Organizing Employee Data

Loaded records are stored in an array, which holds instances of Manager and Developer objects. This array serves as the primary data store for further operations. The design ensures flexibility: the system can dynamically handle any number of records, with a minimum of 7-10 for demonstration purposes.

User Interaction and Record Display

The user interface enables selecting how many records to view, with a default start at three per type. Controls, such as dropdown menus or input fields, allow users to specify the number of records to display, up to the total loaded. The program then filters and displays the corresponding records, segregating managers and developers as necessary, with clarity and readability. It employs dynamic DOM updates or console outputs, depending on the platform.

Comments and Code Flow Explanation

Throughout the implementation, clear comments document class definitions, data processing logic, control flow, and error handling. These annotations facilitate understanding, maintenance, and future modifications, emphasizing good coding practices.

Conclusion

This system exemplifies essential software development skills, combining OOP inheritance, file processing, dynamic data handling, and user interaction. Such an application can be expanded with database integration, search functionalities, and GUI enhancements, making it suitable for enterprise use cases where employee data management is crucial.
