Answer:

B. GRID COMPUTING , ON - DEMAND COMPUTING AND REAL TIME COMPUTING

Explanation:

Grid computing, on-demand computing and real time computing are currently the most impactful information technology processes. The Grid computing from example entails distributed computing whereby computing resources are distributed across different systems for a computing task. This is seen in server systems where a super virtual computer composed of a network of computers are connected to share resources and perform large tasks. This form of computing has majorly affected and improved complex computing tasks today.

On demand and real time computing are also other notable trends in IT with real time computing bringing the power of live and direct coverage of information to our screens and on demand making it possible for the average user to access computing resources as needed such as in the services of cloud computing providers

In this exercise you will debug the code which has been provided in the starter file. The code is intended to take two strings,
vampirchik [111]

Answer:

Here is the corrected program:

import java.util.Scanner; //to accept input from user

public class 02_14_Activity_one { //class name

    public static void main(String[] args) { //start of main method

    Scanner scan = new Scanner(System.in); //creates Scanner class object

  System.out.println("Enter first string"); //prompts user to enter first string

          String s1 = scan.nextLine(); //reads input string from user

  System.out.println("Enter second string"); //prompts user to enter second string

          String s2 = scan.nextLine(); //reads second input string from user

    System.out.println("Enter number of letters from each word"); //enter n

          int n = scan.nextInt(); //reads value of integer n from user

          System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));

         } } //uses substring method to print a string made up of the first n letters of s1 and the last n letters of s2.

Explanation:

The errors were:

1.

Scanner scan = Scanner(System.in);

Here new keyword is missing to create object scan of Scanner class.

Corrected statement:

 Scanner scan = new Scanner(System.in);

2.

String s1 = nextLine();  

Here object scan is missing to call nextLine() method of class Scanner

Corrected statement:

String s1 = scan.nextLine();

3.

String s2 = Scanner.nextLine();

Here class is used instead of its object scan to access the method nextLine

Corrected statement:

String s2 = scan.nextLine();

4.

String n = scan.nextLine();

Here n is of type String but n is a whole number so it should be of type int. Also the method nextInt will be used to scan and accept an integer value

Corrected statement:

int n = scan.nextInt();

5.

System.out.println(s1.substring(1,n-1) + s2.substring(s1.length()-n));

This statement is also not correct

Corrected statement:

System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));

This works as follows:

s1.substring(0,n) uses substring method to return a new string that is a substring of this s1. The substring begins at the 0th index of s1 and extends to the character at index n.

s2.substring(s2.length() - n ) uses substring method to return a new string that is a substring of this s2. The substring then uses length() method to get the length of s2 and subtracts integer n from it and thus returns the last n characters of s2.

The screenshot of program along with its output is attached.
