Answer:
The correct answer is d.extended.
Explanation:
In order to have a superclass in Java, it is indispensable to extend, or inherit from, a class. It means that a subclass is created by an extended class. All the classes in Java only need one superclass from which it inherits some of its fields and methods.
Any test practices end-user he or she does by step by step process for quality testing. Some end-user will have a checklist to do while testing any software or hardware installing.
A hacking end-user has to do the test process if he or she has to follow some steps during testing.
<u>Explanation:</u>
This process is called penetration testing, in other words, it is called pen-testing.
1. In the digital world, security plays an important role. Before any potential incidents taking place, security threats have to handle properly. Before hacking takes place for pc or workstation or desktop, the end-user has to identify and take proper action.
Mostly all threats happen in c:\users\appdata folder in windows operating system
2. Penetration testing is used to for hacking purpose testing.
a. Step by step method is followed.
b. Best practice testing on network security, computer system, web system and find vulnerability check.
c. The pen test method is involved in legal achievements on network
d. To identify vulnerability assessment inside a network
Answer: Insertion steganography
Explanation: Insertion steganography is the way of encrypting the data with the help of a regular files and message. It is encrypted by the ordinary files because the identification of files can be neglected. This process is carried out just for the protection purpose in extra form and gets decrypted in the destination port .It has the working based on the replacement of the bits in a file .
Answer:
The code will give an error that is "At least one public class is required in main file".
Explanation:
In the given code if we do not use the public access modifier to the class. It will give an error so, the correct code to this question as follows:
Program:
import java.util.HashSet; //import package
public class A //define class as public.
{
public static void main(String[ ] args) //define main method.
{
HashSet set = new HashSet(); //creating hashset object.
set.add("A"); //add alphabet in hashset
set.add("B"); //add alphabet in hashset
set.add("C"); //add alphabet in hashset
System.out.print("Size of HashSet is :"set.size()); //print the size of hashset.
}
}
Output:
Size of HashSet is : 3
Explanation of the program:
- In the above program, we define a public class that is "A" and inside the class, we define the main method.
- Inside the main method, we create a HashSet class object that is "set".
- To add elements in HashSet we use add() function that adds elements and in the last, we use the size() function that prints the size HashSet.
Oh a document, I do not believe that you have type on images, but if you were to type a text in a app called PicsArt and saved it and then put it onto the document over the picture it would work.
