Explanation of Solution

Changes need for Listing 12.1:

• User need to change the import statement “import java.util.ArrayList;” to “import java.util.LinkedList;”
• Then there is a need to make a change in invoking constructor.
  • That is change “LinkedList<String> toDoList = new LinkedList<String>();” to “LinkedList<String> toDoList = new LinkedList<String>();”.

Modified code from Listing 12.1:

The modified code for Listing 12.1 is given below:

//Import required package

import java.util.LinkedList;

import java.util.Scanner;

//Define "ArrayListDemo" class

public class ArrayListDemo

{

  //Define main function

  public static void main(String[] args)

  {

  /* Create an object for "LinkedList" class */

LinkedList<String> toDoList = new LinkedList<String>();

  /* Display prompt statement */

System.out.println("Enter items for the list, when prompted.");

/* Assign variable "done" to "false" */

boolean done = false;

/* Create object for "Scanner" class */

Scanner keyboard = new Scanner(System...
