23 Pages Of Java Code All Java Filesat This Point You Are Ready To

23 Pages of Java code including all Java files. At this point, you are ready to develop Java code to ask questions about customer information and the sub sandwich that customers want to order. You should focus on creating functionality to request and provide feedback on customer inputs. Your primary task is to define your classes and abstract classes, utilizing inheritance and polymorphism for the final sub the customer orders. First, prompt for the customer name and delivery address, then prompt for the beverage, sub bread, sub type, and sub size. Echo back all entered information with a message, similar to: "Customer Name: [name]\nDelivery Address: [address]\nBeverage: [beverage]\nBread: [bread]\nType: [type]\nSize: [size]". Be sure to prompt for all four attributes necessary for defining the final sub and beverage selection. Comment all your code to demonstrate understanding.

Deliverables include updating the title page of the Design Document with the project name (Unit 2 IP) and date, adding a section header "Phase 2 Application Screenshots," including screenshots of each application screen, naming the document "yourname_ITSD424_IP2.doc," and submitting the Design Document and zipped Java project files for grading.

Paper For Above instruction

Introduction

The process of developing a Java application that captures customer information and preferences for a sub sandwich order involves designing an object-oriented structure that effectively utilizes inheritance and polymorphism. This paper discusses the implementation of such a system, focusing on class design, user input handling, and providing feedback to the customer. The goal is to facilitate a user-friendly interface that prompts for necessary details, dynamically represents different sub and beverage types, and echoes the entered information back to ensure accuracy. Additionally, the paper covers the importance of well-commented code for maintainability and clarity, along with specific deliverables such as screenshots, documentation updates, and project packaging.

Design and Implementation of the Java Ordering System

The core of the programming task centers on creating a modular, scalable Java system capable of capturing customer details and their sandwich preferences. The design commences with defining base classes and abstract classes that encapsulate common features of beverages and sub sandwiches, leveraging inheritance for variations such as different sub types and drink options.

Class Design and Inheritance

At the foundation, an abstract class 'OrderItem' could be established to represent a general item in an order, with properties like description, size, and price. Two subclasses, 'SubSandwich' and 'Beverage,' extend this class to specify particular attributes and behaviors. For example, 'SubSandwich' might include attributes like bread type, sub type, and special instructions, while 'Beverage' might focus on drink size and type.

Inheritance enables creating specific categories such as 'VeggieSub' or 'MeatSub,' inheriting from 'SubSandwich,' allowing for flexible extension and customization of sandwich options. Polymorphism is employed when handling a list of 'OrderItem' objects, enabling uniform processing regardless of specific subtypes.

User Interaction and Input Handling

The application begins by prompting the user for their name and delivery address, stored in variables. Subsequently, it asks for beverage choice, bread type, sub type, and size, using scanner input methods. After capturing each detail, the program constructs objects representing the selected items, utilizing constructors from the subclasses.

To ensure correctness, all prompts are followed by echo statements that display the entered information, confirming with the customer before finalizing the order. For example:

"Customer Name: John Doe",

"Delivery Address: 123 Elm Street",

"Beverage: Coke, Large",

"Sub Bread: Wheat",

"Sub Type: Veggie",

"Size: Medium".

This feedback loop minimizes input errors and enhances user experience.

Code Comments and Maintainability

Throughout the Java classes, comments explicitly describe the purpose of classes, methods, and variables. For instance, the constructor methods specify what attributes they initialize, and functions for displaying order details clarify their output. Commenting is essential for future modifications, understanding logic flow, and ensuring code clarity for collaborators or future developers.

Deliverables and Documentation

Key deliverables include updating the project’s title page with the project name and date, introducing a new section titled "Phase 2 Application Screenshots," and capturing screenshots of each application's screen state—such as input prompts, confirmation messages, and final order display. These visuals are compiled into a Word document named "yourname_ITSD424_IP2.doc," alongside the complete Java source code zipped in a package for submission. Proper documentation and visualization support validation of functionality, user experience, and adherence to project requirements.

Conclusion

Developing a Java-based order entry system for a sandwich shop emphasizes core object-oriented principles such as inheritance and polymorphism. By structuring classes appropriately, handling user input meticulously, and providing clear feedback, the application becomes both robust and user-friendly. Proper commenting enhances maintainability, and thorough documentation, including screenshots and organized code, ensures successful evaluation and scalability for future features.
