1 PhoneBook (Sorting) Background: You will be modifying your PhoneBook class to sort by different fields in a contact. Assignment: 1. Create a project called PhoneBookSort. Copy your PhoneBook class and Contact class from the PhoneBook project you completed earlier. 2. Add an additional constructor to the PhoneBook class. It should take a single parameter: a String which is the name of a file that holds saved contact information. In this method, you are to open the file and read in all of the contacts and added them to your ArrayList. Each contact in the file is on a single line. The contacts are in two forms: Name PhoneNumber Name PhoneNumber SpeedDial 3. You should add 3 public static final variables to the PhoneBook class: public static final int SORT_BY_NAME = 100; public static final int SORT_BY_PHONE_NUMBER = 200; public static final int SORT_BY_SPEED_DIAL = 300; 4. You will need to create 3 new classes that implement the Comparator interface for sorting Contacts: a. For SORT_BY_NAME, you will sort by the names in the phone book. b. For SORT_BY_PHONE_NUMBER, you will sort by the phone numbers in the phone book. c. Sorting for SORT_BY_SPEED_DIAL is more complicated. The first items in the sort should be the contacts with a speed dial, sorted by the speed dial number. Following the contacts with a speed dial should be the rest of the contacts sorted by name. 5. Modify the printphonebook method to accept one of the above 3 values. You should then change the printphonebook code to sort prior to outputting the data in the phone book. // // Loop through the ArrayList and prints the name and phone number for all // contacts. // If the phone book is empty, output // // The phone book is empty // public void printphonebook(int howtosort) { } a. For SORT_BY_NAME, use the comparator class you created to sort by name, and the output will look as it did before: // Name, Phone (SpeedDial) // or // Name, Phone b. For SORT_BY_PHONE_NUMBER, use the comparator class you created to sort by phone number. The output will change so that phone number comes first with a speed dial in parentheses if it exists: // Phone, Name (SpeedDial) // or // Phone, Name

2 c. For SORT_BY_SPEED_DIAL use the comparator class you created to sort by speed dial. The output changes as well: // SpeedDial Name, Phone // or // Name, Phone d. For any other value, throw an exception. What would be a good exception to throw? Driver: The PhoneBook.txt file should be downloaded and placed in the PhoneBookSort project before running the program. public class PhoneBookDriver { public static void main(string[] args) { PhoneBook pb = new PhoneBook("PhoneBook.txt"); System.out.println("SORT BY NAME"); pb.printphonebook(phonebook.sort_by_name); System.out.println("SORT BY PHONE NUMBER"); pb.printphonebook(phonebook.sort_by_phone_number); } } System.out.println("SORT BY SPEED DIAL"); pb.printphonebook(phonebook.sort_by_speed_dial); Output: SORT BY NAME Albert, Alex, Amy, Annabelle, Ashley, Avery, (9) Barbara, Billy, Bob, Brian, (2) Chad, Christine, Christy, Cindy, David, Debbie, Dennis, Diane, Donna, Edward, Elizabeth,
