Overview In This Assignment You Will Be Implementing 7 Total Classes T

In this assignment, you will be implementing seven classes that simulate a payroll system for employees of a startup company. A superclass named Employee is provided, and the first six classes will subclass from Employee. All instance variables are private and require appropriate getter and setter methods. All instance methods are public.

The subclasses to be implemented are BoardMember, Engineer, Accountant, Custodian, Marketer, and Intern. Each subclass has specific attributes, constants, and methods concerning vacation days, health insurance, income, and other relevant metrics. The classes also override certain methods from Employee, such as YTDValue() and yearsTillRetirement(), with specific calculation formulas provided.

The Payroll class manages an array of Employee objects, with methods to sort employees by their retirement date or their Year-To-Date (YTD) value. The sorting methods order employees based on their retirement year or their current YTD earnings, respectively.

Your task involves creating these classes with correct attributes, encapsulation, inheritance, method overriding, and sorting functionalities according to the specifications provided.

Paper For Above instruction

This paper presents a detailed implementation plan for a payroll simulation system that models various employee types within a startup company. The system comprises a superclass Employee and six subclasses—BoardMember, Engineer, Accountant, Custodian, Marketer, and Intern. Additionally, a Payroll class orchestrates the management and sorting of employee data. The design emphasizes encapsulation, inheritance, method overriding, and precise calculations, aligning with object-oriented programming best practices.

Introduction

In any organizational payroll system, accurately modeling different employee types with specific attributes and behaviors is paramount. This system leverages inheritance to define shared characteristics within the Employee superclass, while subclasses customize their behaviors and attributes to reflect their unique roles and compensation structures. The Payroll class serves as a manager that facilitates sorting and organizing employees based on specific criteria, such as retirement timelines and earnings.

Design and Implementation of Employee and Subclasses

The Employee superclass encapsulates common features such as years worked, vacation days, sick leave, and methods to manipulate these variables. The subclasses extend this base class, introducing role-specific constants like bonuses, health insurance, income levels, and methods for vacation usage and work-year progression. For instance, the BoardMember class includes additional attributes such as a yearly bonus, vacation days, health insurance, and methods to handle unpaid and paid vacation, sick days, and calculating the YTDValue and retirement year estimates.

Each subclass contains constants that define its compensation and benefits, such as bonuses, vacation days, health insurance, and income. Methods to track usage of paid and unpaid vacations, sick leave, and work progression are also provided. The overriding methods, YTDValue and yearsTillRetirement, are implemented according to detailed formulas, ensuring accurate and dynamic calculations based on the employee’s activity and status.

Specifics of Method Overriding and Calculations

The YTDValue method computes annual earnings by summing fixed bonuses, health insurance benefits, income proportional to days worked, and adjustments for sick leave. For example, the BoardMember class’s YTDValue incorporates a bonus, health insurance, income, paid vacation earnings, and sick leave adjustments, all calculated based on 260 working days annually. Similarly, yearsTillRetirement estimates the remaining working years before retirement, considering current years worked, used unpaid vacation days, used paid vacation days, and used sick days, with a cap at zero to avoid negative values.',

The Payroll Class and Sorting Functions

The Payroll class maintains an array of employee objects and provides methods to sort employees either by their retirement date or by their current earnings (YTDValue). Sorting is performed in descending order, with employees who retire soonest or have the highest earnings positioned at the start of the array. Implementing efficient sorting algorithms, such as bubble sort, insertion sort, or utilizing Java’s built-in Arrays.sort with custom comparators, ensures the flexibility and robustness of the payroll system.

Conclusion

This architecture demonstrates a comprehensive application of object-oriented principles in designing a payroll system that accommodates diverse employee profiles. The careful calculation methods, encapsulation, inheritance, and sorting functionalities collectively enable a dynamic and scalable payroll management solution capable of adapting to organizational changes and growth.
