Design An Employee Class With Specified Fields

Design An Employee Class That Has Fields For the Following Pieces Of I

Design an Employee class that has fields for the following pieces of information: Employee Name and Employee Number. Then, design a class named ProductionWorker that extends the Employee class. The ProductionWorker class should include fields for Shift Number (an integer, such as 1, 2, or 3) and Hourly Pay Rate. The workday has two shifts: day (shift 1) and night (shift 2). The shift field will hold an integer representing the shift that the employee works. The day shift is shift 1, and the night shift is shift 2. Design appropriate accessor and mutator methods for each class. After designing the classes, create a program that instantiates a ProductionWorker object, prompts the user to enter data for each field, stores the data in the object, and then retrieves and displays the data using the object's accessor methods. Submit your Java source code (with comments) and the flowchart (RAPTOR file) of your program, ensuring it is error-free and functions correctly.

Design An Employee Class That Has Fields For the Following Pieces Of I

The task involves designing an object-oriented system in Java that models employees and specifically production workers within an organization. It comprises creating a base Employee class and a derived ProductionWorker class, together with a functional program that collects data from users, stores it, and displays it. This approach demonstrates inheritance, encapsulation, and user interaction in Java programming.

Designing the Employee Class

The Employee class serves as the foundational class representing general employee information. It encapsulates essential attributes such as the employee’s name and employee number. These fields are kept private to prevent unauthorized external access and promote data integrity, adhering to the principle of encapsulation. The class provides public accessor (getter) and mutator (setter) methods to interact with these fields, allowing controlled access and modification.

The Employee class layout is straightforward:

  • Private Fields: Employee Name (String), Employee Number (int or String)
  • Constructor: to initialize these fields
  • Accessor Methods: getEmployeeName(), getEmployeeNumber()
  • Mutator Methods: setEmployeeName(), setEmployeeNumber()

Designing the ProductionWorker Class

The ProductionWorker class inherits from Employee, representing a specialized type of employee with additional attributes. It introduces fields for shift number and hourly pay rate, both crucial for production workers. The shift field indicates which shift the worker is assigned to, with conventions: 1 for day shift and 2 for night shift.

Again, encapsulation is employed by declaring these fields as private and providing public getter and setter methods:

  • Private Fields: shiftNumber (int), hourlyPayRate (double)
  • Constructor: to initialize inherited and new fields
  • Accessor Methods: getShiftNumber(), getHourlyPayRate()
  • Mutator Methods: setShiftNumber(), setHourlyPayRate()

Implementing the Program to Use These Classes

The main program prompts the user to input data for an instance of ProductionWorker, including name, employee number, shift, and hourly pay rate. After collecting the data through the Java Scanner class, it stores the inputs in the object's fields using setter methods. Subsequently, it retrieves and displays the data using getter methods, illustrating the principles of object-oriented programming in Java.

This approach ensures data encapsulation, reusability, and clarity in the code structure. Comments are added throughout the source code to explain each logical step, making the program understandable and maintainable.

Summary

Overall, this project demonstrates inheritance by extending the Employee class to create the ProductionWorker class. It emphasizes encapsulation by using private fields with public accessors and mutators. The interactive program highlights practical application by gathering user input and presenting stored data. Proper class design, method implementation, and user interaction collectively illustrate core Java programming principles.
