Answer:
Quarantine the computer.
Explanation:
Malware can be characterized with negative software capable of causing various damages to a computer, such as theft of data and information, in addition to damage to devices.
In order to avoid having your computer infected with malware, it is essential to have installed reliable malware-checking software, in addition to taking all appropriate security measures when accessing the internet and never clicking on unknown or suspicious links.
Therefore, when realizing that the computer has been infected by malware, it is necessary to quarantine the computer and immediately disconnect from a network so that it does not infect other computers. The quarantine acts as an action where the infected file is moved to an encrypted folder where the malware cannot be executed and spread by the operating system.
Answer:
The code to this question can be given as:
Code:
public class Book //define class.
{
private String title, author; //define variable.
Book(String a, String b) //define parameterized constructor.
{
title = a; //holding value.
author = b;
}
public String toString() //string function
{
return title + "\n" + author; //return value.
}
}
Explanation:
In the above java code firstly we declare the class book that name is already given in the question. Then we declare the private variable that datatype is string author and title. Then we declare the parameterized constructor. In the parameterized constructor we use the private variable for hold constructor parameter value. Then we declare the tostring() function in this function we return value of the title and author variable.
Answer:
0.
Explanation:
Given
int x;
x=3/(int)(4.5+6.4)
Required
What is x?
The first line of the code segment declares x as integer. This means that, it will only hold non decimal numbers.
With the above explanation, options (a), (c) and (d) can not be true.
Solving further:
x=3/(int)(4.5+6.4)
The computer evaluates the denominator as:
x=3/(int)(10.9)
The denominator is then converted to an integer. So, we have:
x = 3/10;
3/10 = 0.3 but
Recall that: <em>x will only hold non decimal numbers.</em>
So:
x = 0;

Answer:
1. True.
2. False.
3. True.
4. True.
Explanation:
Remember OR operator (||) gives false when both of it's operands are false. AND Operator (&&) gives false when even one of it's operator is false.
In first part we have
!(True || False) || True
=!True||True
=False||True
=True
In second part we have.
False && True && True
= False && True
=False.
In Third part
! True || (False || True)
=False || True
=True.
In fourth part
True || True && False
=True|| False
=True.
