In an earlier assignment you modeled an inheritance hierarchy for dog and cat pets. You can reuse the code for that hierarchy in this assignment. Write a program that prompts the user to enter data (name, weight, age) for several Dog and Cat objects and stores the objects in an array list. The program should display the attributes for each object in the list, and then calculate and display the average age of all pets in the list using a method as indicated below:

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

 {

   BufferedReader data =

     new BufferedReader (new InputStreamReader (System. in));

   //Define variables

n = data.readLine ();

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: ");

 for (Pets arraypet:arraypets)

     {

System.out.println (arraypet);

     }

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

   System.out.println ("Average age of all pets in the list: " + average);

True or False: A base register is used to transform physical addresses (generated by the program) into virtual addresses.

Answers

False, a base register is not employed to convert physically generated addresses into virtual addresses.

How does the base & bounds method translate virtual memory addresses?

Each memory reference's virtual address and bound register are checked, and the result is added to the base register to create the physical address. An operating system trap is set off by a bound violation. The bound register appears to control the extent of a wholly private memory that is shared by all processes.

A desktop computer does not have a lit link light on the back of the computer. Which of the following is the most likely reason for this

Answers

The desktop computer is not connected to a network cable, so there is no need for a link light.

What type of connection is the computer using? The type of connection a computer is using depends on the type of device that is being used to connect to the Internet. For example, if the computer is connecting to the Internet via a modem, then it is using a dial-up connection. Dial-up connections are slow, but they are still used in some rural areas where other options are not available. Alternatively, if the computer is using an Ethernet cable to access the Internet, then it is using a wired connection. Wired connections are more reliable than dial-up connections, but they require access to a physical network such as a router.Wireless connections are also popular for connecting to the Internet. Wireless connections use radio waves to transmit data, allowing users to connect without a physical connection. This can be done via a Wi-Fi router or a cellular data connection, such as 3G or 4G. Wi-Fi connections are typically faster than wired connections, but they are also more vulnerable to interference and can be difficult to set up.Finally, some computers are able to use satellite connections to access the Internet. These connections are typically slower than wired or wireless connections, but they can be used in places where other options are unavailable. Satellite connections can be expensive, however, so they are not always the best option.

Answers

True,  with pointer variables you can access, but you cannot modify, data in other variables.

Which regarding a pointer variable is true?

A pointer variable, also referred to as a pointer or just a pointer, functions similarly to other variables that can hold data. A pointer saves a memory address instead of a value like a conventional variable would (such as an int, double, or char). Similar to a regular variable, pointers must be declared before they may be utilized.

Why not use variables instead of pointers?

In essence, a pointer can be used to point to any variable of the same type (e.g. any integer, double, char, etc.).

                            The values of numerous distinct variables of the same type can be updated or changed using this method. Using pointers speeds up execution as well. More quickly can be accessed memory.
