The error in your Java program is described as follows:

You cannot print a string without setting its value.

<h3>How to print a string in Java?</h3>

There are multiple ways to print a string in a Java, but one of them is using the system.out.println(string) command, which prints the string and gives a new line.

However, for this method, and any other, the string has to be set before it is printed, which does not happen for this problem. There should be a line setting the string like the example:

s = "ABC";

Hence the correct option regarding the error is given as follows:

You cannot print a string without setting its value.

Answer:

B. SSD

Explanation:

VMs or virtual machines are virtually created environment for multiple operating system on a host operating system. The host operating system has an extension called Hyper-V. The hyper-V manager helps to manage the virtual machine's activities.

The VMs can hold applications in their respective containers, which requires a partition of the storage. So when more VMs are configured, more storage memory is required to store their individual data. The VMs in a computer system can share a network interface card.

In a <u>little endian computer</u> -The data's least substantial byte is put at the lower address byte. The remaining information will be put in memory in order in the next three bytes.

a)1234

4 is placed at the least significant bits,so this byte stored at lower memory address.

1 is placed at the most significant bits,so this byte stored at higher memory address.

b) ABFC

C is placed at the least significant bits,so this byte stored at lower memory address.

A is placed at the most significant bits,so this byte stored at higher memory address.

c) B100

0 is placed at the least significant bits,so this byte stored at lower memory address.

B is placed at the most significant bits,so this byte stored at higher memory address.

d) B800

0 is placed at the least significant bits,so this byte stored at lower memory address.

In the most common use of the term, a class can be seen as a blueprint used to create objects. In other words, object(s) are created from a class in Java.

<h3>Creating a Class</h3><h3>Code:</h3>

import java.util.*;

class Card{

 private String suit;

 private int value;

 public Card(String s,int v){

   suit = s;

   value = v;

 }

 public String getSuit(){

   return suit;

 }

 public int getValue(){

   return value;

 }

 public void display(){

   System.out.println(value+"("+suit+")");

 }

}

class Deck{

 private ArrayList<Card> deck;

 private ArrayList<Card> drawn;

 public Deck(){

   deck = new ArrayList<Card>();

   drawn = new ArrayList<Card>();

   String[] arr = {"Club","Spade","Heart","Diamond"};

   for(String s : arr){

     for(int i=1;i<=13;i++){

       deck.add(new Card(s,i));

     }

   }

 }

 public void draw(){

   drawn.add(deck.get(0));

   deck.remove(0);

 }

 public void draw(int N){

   if(N > deck.size()){

     N = deck.size();

   }

   for(int i=0;i<N;i++){

     draw();

   }

 }

 public void showDrawn(){

   for(Card c : drawn){

     c.display();

   }

 }

 public void shuffle(){

   Collections.shuffle(deck);

 }

 public void restore(){

     drawn.remove(0);

   }

 }

 public void showDeck(){

}

class Test{

The Matlab Script should:1. Clear the command window2. Clear the workspaceQuestion 1: Why do we clear the command window and wor
finlep [7]

Answer:

This is done for the simple reason of having more space to work on

Explanation:

This is done for the simple reason of having more space to work on. By clearing the command window and workspace you provide yourself with sufficient space to create new commands without the clutter of the previous commands. This also prevents your focus from shifting towards old commands and allows you to simply focus on the commands you are currently working on. This does not clear all variables from the script, it only clears the current screen but the previous commands can still be accessed by using the up-arrow key
