02. Second Assignment The FacebookUser Class

Were going to make a small change to the UserAccount class from the last assignment by adding a new method:

public abstract void getPasswordHelp(); 

This method is abstract because different types of user accounts may provide different types of help, such as providing a password hint that was entered by the user when the account was created or initiating a process to reset the password. Next we will create a subclass of UserAccount called FacebookUser. The FacebookUser class needs to have the following fields and methods in addition to what is in UserAccount:

Fields:

String passwordHint ArrayList friends 

Methods:

void setPasswordHint(String hint) void friend(FacebookUser newFriend) void defriend(FacebookUser formerFriend) ArrayList getFriends() 

The friend method should add the FacebookUser argument to the friends ArrayList (if that FacebookUser is already in the friends list, display an error message), and the defriend method should remove the FacebookUser argument from that ArrayList (if that FacebookUser is not in the friends list, display an error message). The getFriends method should return a copy of this users friends create a new ArrayList with the same FacebookUsers in it as this users friends. Do not return the friends ArrayList directly, since this violates the principle of encapsulation. The getPasswordHelp method should display the passwordHint. The FacebookUser class should also implement the Comparable interface. FacebookUsers should be sorted alphabetically by username, ignoring capitalization. (Hint: notice that the toString method returns the username of the UserAccount.) Finally, write a driver program that creates several FacebookUsers and demonstrates the user of the setPasswordHint, friend, defriend, getFriends, and getPasswordHelp methods. Also, put the FacebookUser objects into an ArrayList,

sort them (see the jar file for this topic for help on this), and print them out in sorted order.

This is my code please help fix:

//Facebook driver

import java.util.ArrayList; import java.util.Collections; import java.util.List;

public class facebookDriver1 {

public static void main(String[] args) { // TODO Auto-generated method stub FacebookAccount account1= new FacebookAccount("Venessa Black","fl11"); FacebookAccount account2=new FacebookAccount("Jack Lord","Flyon"); FacebookAccount account3=new FacebookAccount("Daniel MStar","Straight"); FacebookAccount account4=new FacebookAccount("Noah Ark","Flatscreen"); System.out.println(" ");

account1.setPasswordHint("bestfriends name"); account1.get_Help(); account1.friend(account2); account1.friend(account3); account1.friend(account4);

System.out.println("Venessa's friends"+account1.getFriends());

account1.defriend(account2); account1.defriend(account2);

ArrayListfriends=new ArrayList(); friends.add(account1); friends.add(account2); friends.add(account3); friends.add(account4); System.out.print("Unsorted"); for(FacebookAccount faceBook:friends) {System.out.println(" friends FacebookAccount:"+faceBook); } Collections.sort(friends); System.out.print("Sorted :"); for(FacebookAccount facebook:friends) { System.out.println("friends FacebookAccount:"+facebook); } System.out.println(" "); } }
