Code Explanation:

The provided Java code snippet simulates a simple Smart Home environment using the principles of Internet of Things (IoT). Below is a detailed explanation of the code:

• SmartDevice Interface: This interface declares common methods (turnOn(), turnOff(), and isOn()) that all smart devices will implement. By using an interface, we maintain a level of abstraction and ensure that any device we create will have these fundamental functionalities.
• SmartBulb and SmartThermostat Classes: These classes implement the SmartDevice interface. They simulate smart bulbs and thermostats, respectively, with turnOn(), turnOff(), and isOn() methods. Each method is accompanied by a print statement to simulate the device’s state on a console.
• SmartHomeHub Class: This class acts as a central hub managing an array of SmartDevices. The addDevice() method allows devices to be added to the hub. The activateAllDevices() and deactivateAllDevices() methods iterate over the attached devices, turning them on and off respectively.
• SmartHomeSimulation: This is the main class containing the main() method where the program starts its execution. Here, we create an instance of SmartHomeHub and then instantiate a SmartBulb and a SmartThermostat. These devices are added to the hub, which is then instructed to activate and subsequently deactivate all of them, to simulate a real smart home scenario.

This code acts as a foundation for a robust Smart Home IoT project. It can be expanded by adding more devices, implementing more complex device interactions and automations, and integrating with actual hardware.
