Java Swing Pizza Store Simulation

Academic work, I need all the codes to run it properly Project Description We need a desktop application for a pizza store that sells pizzas based on their area (in square centimeters) instead of the traditional sizes (small, medium, large). The application should manage customers, orders, and pizza flavors, and allow for price adjustments and order tracking. The system must be implemented in Java using the MVC (Model-View-Controller) architecture and must include a graphical user interface (GUI) built with Java Swing. The application will calculate the price of pizzas based on their area and the selected flavors, which are categorized into Simple, Special, and Premium. Key Features 1. Customer Management: • Add, edit, list, and delete customers. • Filter customers by last name, part of the last name, or phone number. • Automatically delete all orders related to a customer when the customer is deleted. 2. Pizza Order Management: • A customer must be selected before placing an order. • The user can choose: • Shape of the pizza: Circle, Square, or Equilateral Triangle. • Dimensions: • Circle: Radius (7–23 cm). • Square: Side length (10–40 cm). • Triangle: Side length (20–60 cm). • Alternatively, specify the area (minimum 100 cm², maximum 1600 cm²), and the system should calculate the dimensions. • Flavors: Up to 2 flavors per pizza, each associated with a pizza type (Simple, Special, Premium). • The system calculates the total price based on the area and selected flavors. If two flavors are selected, the price is the average of the two types. • Add multiple pizzas to the same order. • Modify an existing order. • Store each order with a unique identifier, the list of pizzas, and the total price. 3. Price Management: • Update the price per square centimeter for each pizza type (Simple, Special, Premium). 4. Flavor Management: • Add new flavors and associate them with a pizza type (Simple, Special, Premium). 5. Order State Management: • Each order can have one of three states: Open, In Progress, or Delivered. • A dedicated screen should allow the user to view all orders, their states, and update the states. 6. Validations and Error Handling: • Validate user input for fields such as pizza dimensions and customer details. • Inform users of invalid values with clear error messages. • Handle exceptions gracefully. 7. Technology Requirements: • Use Java for development. • Follow the MVC architecture. • Use Java Swing for the graphical user interface. Deliverables 1. Class Diagram: • A complete diagram of all classes, including their relationships. 2. Code and Project: • A fully functional project implemented in an IDE like Eclipse or NetBeans. • The source code must be well-documented and organized. 3. Executable File: • A .jar file to run the application. 4. Demonstration: • The candidate should provide a walkthrough of the code and demonstrate the working system. Evaluation Criteria • Completeness and correctness of the delivered features. • Code quality and adherence to the MVC architecture. • Proper error handling and input validation. • Functionality of the graphical interface. • The candidate’s ability to explain and defend their implementation. This description should provide any developer or team with a clear understanding of the project’s scope and requirements.
