Java program that shows the use of inheritance hierarchy, the code reuses the attributes of the class objects.

Importance of applying inheritance:

In this case of pets (dogs and cats), applying inheritance allows a much shorter and more structured code. Also, reusable since we can add classes of other pets such as birds, rabbits, etc., all of them also belonging to the Pet superclass.

Reserved words in a java code that enforces inheritance:

extendsprotectedSuper

Here is an example:

Java code

import java. io.*;

import java.util.ArrayList;

import java.io.BufferedReader;

public class Main

// ArrayList of Pet objets

public static ArrayList < Pets > arraypets = new ArrayList < Pets > ();

public static void main (String args[]) throws IOException

aws = data.readLine ();

System.out.print ("Enter name: ");

System.out.print ("Enter weight: ");

str = data.readLine ();

w = Double.valueOf (str);

System.out.print ("Enter age: ");

a = Integer.valueOf (str);

if (aws.equals ("1"))

Cat cat = new Cat (n, w, a);

arraypets.add (cat);

average = cat.averageAges (a);

}

else

{

Dog dog = new Dog (n, w, a);

arraypets.add (dog);

average = dog.averageAges (a);

}

System.out.print ("Enter more data? (y/n)");

aws = data.readLine ();

aws = aws.toLowerCase ();

}

while (!aws.equals ("n"));

//Calculate average of pets age

average = average / arraypets.size ();

average = Math.round (average * 100.0) / 100.0;

// Output

System.out.println ("Attributes for each object in the list: ");

System.out.println ("Number of pets: " + arraypets.size ());

To exhibit high-resolution images, photographers can apply the rule of thirds by positioning the image's component parts along the intersecting lines.

How is the rule of thirds applied?

In order to create a nice composition, the Rule of Thirds positions your topic in the left- or right-third of the frame. Align your main subject and other frame components along these points to produce a balanced, or aesthetically engaging, image. Each intersection point represents a possible focus of interest.

How should the rule of thirds be used when capturing pictures?

___ requires a password when connecting to your router and makes your wireless transmissions unreadable by hackers

Answers

Wi-Fi encryption (such as WPA2 or WPA3) requires a password when connecting to your router and makes your wireless transmissions unreadable by hackers. Wi-Fi encryption is a method of securing wireless communications by encoding the data being transmitted over the airwaves.

This encoding makes it difficult for anyone who intercepts the data to read or understand it. The two most common forms of Wi-Fi encryption are WPA2 (Wi-Fi Protected Access 2) and WPA3. WPA2 uses a process called Temporal Key Integrity Protocol (TKIP) to encrypt the data. TKIP generates a unique encryption key for each packet of data that is sent, making it difficult for hackers to crack the encryption.

WPA3 is the latest version of Wi-Fi encryption. It is more secure than WPA2, and it uses a process called Simultaneous Authentication of Equals (SAE) to encrypt the data.
