Extending the interfaces:

"Yes", it is possible to extend two interfaces exclusively.

Interface:

The interface is similar to the class and it can be declared with the keyword interface.

The interface does not contain any constructors with it and all the methods in the interface are "abstract".

A class only "implements" the interface and it cannot "extends" the interface.

But the interface can extend multiple interfaces.

The interface extends another interface using the "extends" keyword in java.

While extending the interface, the child interface inherits the methods of parent interface.

Sample code:

//Declare the interface Animal

public interface Animal

{

// Create the method run()

public void run();

}

//Declare the interface Goat that extends Animal interface

public interface Goat extends Animal

{

// Create the method

public void milk();

You are tasked with developing a portable system that can be worn to collect health and fitness data. The challenge is to integrate all functions into the smaller form of an ear clip. The device should include heart rate, movement and temperature sensor and wireless communication with a mobile app. Draw a diagram- hardware architecture of the system- including the selection of suitable sensors, communication modules, and an energy-efficient microcontroller. (visualize the components and their connections)

Draw out an example of 3 systems using Lamport’s logical clock and explain the steps in words.
