Publishing House: Flexible Book Registration (JavaBasics_Task_236_V0.1)

📖 Description

In the publishing industry, data arrives in stages. This project models a Book entity that can be registered even if its physical properties (like page count) are not yet finalized. By using Constructor Overloading, the system provides two entry points for data: one for early-stage titles and another for completed manuscripts. This approach ensures that every book in the database is properly initialized, maintaining a high level of data consistency.

📋 Requirements Compliance

• Overloaded Constructors: Provided two distinct ways to instantiate the Book class.
• Default Value Assignment: Automatically sets the page count to 0 when only a title is provided.
• State Management: Used the this keyword to correctly map parameters to instance fields.
• Architectural Separation: Divided the project into Model, Service, and Reporter layers for clean code.
• Naming Conventions: Followed PascalCase for classes and camelCase for variables/methods.

🚀 Architectural Stack

• Java 8+ (Constructors, Method Overloading, SRP)

🏗️ Implementation Details

• Book: The Model. Defines the structure and initialization rules.
• PublishingService: The Logic. Acts as the "Registrar" for new arrivals.
• BookReporter: The View. Formats and displays book information to the user.
• PublishingApp: The Orchestrator. Executes the registration scenario.

📋 Expected result

[PUBLISHING]: Registration complete.
Book: A Mysterious Novel, Pages: 0
Book: Traveling through space, Pages: 500
