Program22_Bookstore.java

/*  Develop a Java application for a bookstore management system. The application needs to handle various operations such as adding new books and managing inventory and to ensure proper organization and modularity, utilize Java packages.
    Design a package structure for the bookstore management system. Additionally, create a sample class within each package to demonstrate its functionality.
    Suggested Package Structure:
    bookstore.book :

    bookstore.inventory : 
        Sample Class: InventoryManager - Provides methods to add new books to inventory, update stock levels, and retrieve book details.
    (A Folder Named 'bookstore' which contains 2 files - 'book' & 'inventory'. 'book' contains definition of 'Book' Class. 'inventory' contains definition of 'InventoryManager' Class. ) */
