abstract class : An abstract class is a class which may or may not include abstract methods and cannot be instantiated but rather can be sub classed. Legal abstract class : The conditions for a class to be considered as legal abstract class are mentioned below: If a class includes abstract methods, then the class must be declared as abstract. The abstract method that is declared within the abstract class must be declared without braces and followed by a semicolon. Interface: Interface is a reference type in Java, which contains a collection of abstract methods. An interface needs to the follow certain conditions such as: One cannot instantiate an interface. Interfaces do not contain any constructors. All methods present in the interface are abstracts. An interface does not contain any instance field. An interface cannot be extended by a class.

I cannot program smart home automation rules from my device using a computer or phone, and I would like to know how to properly connect devices such as switches and sensors together ? Cisco Packet Tracer 1. Smart Home Automation:o Connect a temperature sensor and a fan to a home gateway.o Configure the home gateway so that the fan is activated when the temperature exceedsa set threshold (e.g., 30°C).2. WiFi Network Configuration:o Set up a wireless LAN with a unique SSID.o Enable WPA2 encryption to secure the WiFi network.o Implement MAC address filtering to allow only specific clients to connect.3. WLC Configuration:o Deploy at least two wireless access points connected to a Wireless LAN Controller(WLC).o Configure the WLC to manage the APs, broadcast the configured SSID, and applyconsistent security settings across all APs.
