Smart Home: Hierarchical Data Access (JavaBasics_Task_267_V0.1)

📖 Description

In nested object structures, an inner class often needs to reference the state of its parent instance. This project demonstrates the use of a Non-static Inner Class (Room) within an outer class (House). It highlights the Outer.this syntax, which allows the inner class to explicitly access the outer class's private fields. This is essential for distinguishing between local instance data and the broader context provided by the parent object.

📋 Requirements Compliance

• Inner Class Nesting: Implemented Room inside House to model a physical relationship.
• Outer Reference: Used House.this.houseAddress to retrieve data from the parent instance.
• Constructor Initialization: Both classes use private fields initialized via their respective constructors.
• Access Modifiers: Demonstrated that inner classes have full access to private members of the outer class.

🚀 Architectural Stack

• Java 8+ (Inner Classes, Scoping and Shadowing, Encapsulation)

🏗️ Implementation Details

• House: The outer class representing the global context (address).
• Room: The inner class representing a specific sub-entity (identifier).
• HouseApp: The entry point demonstrating the linked instantiation of House and Room.

📋 Expected result

Room: Master Bedroom
House: Sunny Valley Lane
