Java Assignment: Exploring Classes, Objects, and Inheritance

This Java assignment solution provides a detailed overview of classes, objects, and inheritance, focusing on practical implementation through class definitions like `Test`, `Camera`, `MobilePhone`, and `Tablet`. The `Test` class includes methods for reading repository data and order information, while the `Camera`, `MobilePhone`, and `Tablet` classes demonstrate inheritance and encapsulation with specific attributes and methods for each. The document outlines variable names, data types, and method signatures for each class, including methods for setting warranties, brand names, screen sizes, pixel counts, storage, colors, and operating systems. Additionally, it references external resources for further understanding of Java's object-oriented programming concepts, all available with more solved assignments and study tools on Desklib.
