Design and develop a console (text-based) application for a small catering business. This application will simulate booking appointments, tracking catering jobs, and processing payments. The program must include features such as adding new appointments, listing active jobs, listing unpaid completed jobs, scheduling jobs by day, accepting payments, providing detailed appointment status, and exiting the program. The project requires designing an algorithm, implementing the program with specific programming concepts (arrays, inheritance, polymorphism, overloading), and documenting testing results. The program should follow good coding practices with comments, exception handling, and proper method separation. Data persistence is not required upon exit.

Paper For Above instruction

The development of a console-based application for a catering business requires meticulous planning and implementation to meet the specified requirements. This paper discusses the comprehensive design, implementation strategies, application of object-oriented programming concepts, and testing methodology required for such a project.

Design and Planning

Before commencing programming, designing an algorithm is essential to outline the program's flow and structure. The algorithm begins with presenting a user menu offering options such as adding new bookings, listing active jobs, listing jobs pending payment, scheduling jobs, accepting payments, viewing detailed appointment info, and exiting. Each selection triggers specific methods that handle the internal logic, data processing, and output display. The design should include data structures to store booking information, status updates, and payment details effectively.

Using an Object-Oriented Programming paradigm, the primary entities such as Appointment, Payment, and possibly subclasses for different booking types (full service vs. food-only) need to be modeled. Inheritance can be employed to extend a base class 'Appointment' into specialized classes, incorporating polymorphism for method overriding where applicable.

Implementation Approach

The application's core will revolve around a menu-driven interface that loops until the user chooses to exit. The main class will contain the main method and manage the user interaction. Auxiliary classes will represent each domain entity, such as:

- Appointment: encapsulating customer info, date, service type, status, and cost.

- Payment: tracking amount paid against owed balance.

- ReservationManager: managing collections of appointments, possibly stored in ArrayLists.

ArrayList will be used to manage collections, such as all bookings or specific groups (active, unpaid). For example, a list of appointments currently in progress or scheduled on particular days.

Inheritance could be demonstrated via classes like "FullServiceBooking" inheriting from "Booking," with additional attributes such as staff requirements. Polymorphism may be illustrated through method overriding, such as calculating costs or displaying details differently based on booking type.

Method overloading will allow the application to handle different input scenarios, such as adding appointments with or without special requirements, or accepting partial payments.

Necessary exception handling will trap invalid inputs, ensuring program robustness, such as handling incorrect date formats or non-numeric payment entries.

The program must run continuously, offering the menu options repeatedly until the user opts to exit, at which point no data persistence is necessary.

Functional Requirements

Adding new appointments involves capturing customer details, booking type, appointment date/time, and deposit calculations based on service type (20% for food-only, 30% for full service). Listing active jobs filters appointments scheduled for today and in progress or completed on the same day. Listing unpaid completed jobs requires filtering the appointment collection for completed status with outstanding payments.

The schedule feature prompts the user for a specific date and displays all appointments on that day. Payment acceptance involves selecting a specific appointment, displaying the amount owing, and recording the payment, updating the owed balance accordingly. The system must prevent overpayment and calculate new balances accurately.

Reporting detailed appointment information requires selecting an appointment, then displaying all stored details, including payment status and overall costs.

The application design emphasizes code readability, maintainability, and adherence to object-oriented principles. Proper encapsulation, method separation, robust input handling, and comments are integral to high-quality implementation.

Testing Strategy

Testing involves simulating various user actions, such as adding appointments, processing payments, and retrieving reports. For each test case, the input sequence, expected output, and actual results must be documented. Screenshots should be included to evidence correct functionality, such as displaying active jobs, unpaid balances, and detailed appointment summaries.

Various scenarios should be tested, including:

- Booking different types of appointments

- Handling invalid inputs (dates, numeric entries)

- Processing partial and full payments

- Listing appointments on specific dates

- Canceling and rescheduling appointments

This testing ensures the application operates as intended under normal and edge cases, affirming its reliability and correctness.
