To modify the existing SmartHomeAutomation code to include an abstract class SmartDevice with an abstract method performAction() that each device and its subclasses (Light, Thermostat, SecurityCamera) will implement, follow these steps:

Create Abstract Class SmartDevice:

Define an abstract class SmartDevice with an abstract method performAction(). Modify Device and Subclasses:

Modify Device, Light, Thermostat, and SecurityCamera to extend SmartDevice. Implement the performAction() method in each subclass to define specific actions for each device. Here’s how you can integrate these changes into your existing code:

} Explanation: Abstract Class SmartDevice:

Introduced an abstract class SmartDevice with an abstract method performAction(). Each subclass (Device, Light, Thermostat, SecurityCamera) extends SmartDevice and implements performAction() with specific behavior. Subclass Implementations:

Each subclass (Light, Thermostat, SecurityCamera) overrides performAction() to define actions appropriate for their functionality (brightness adjustment, temperature setting, recording). Main Method:

Example usage remains the same, showcasing how devices are added to SmartHomeSystem, listed, iterated through, sorted, and used in a Swing GUI interface. This structure ensures that each device type can perform its unique actions through the performAction() method, adhering to the principles of object-oriented design and abstraction.
