hello out there i don't seem to get the last part of this right how am i supposed to fix my code so that it can provide the names provided in the args on the console.

public class ForumPost {
  private User mAuthor;
  private String mTitle;
  private String mDescription;

  public ForumPost(User author, String title, String description) {
  mAuthor = author;
    mTitle =title;
    mDescription = description;


  public String getDescription() {
  return mDescription;

  public User getAuthor() {
    return mAuthor;

  public String getTitle() {
    return mTitle;

  // TODO: We need to expose the description
public class User {

  private String mFirstName;
  private String mLastName;

  public User(String firstName, String lastName) {
    // TODO:  Set the private fields here
    mFirstName =firstName;
    mLastName = lastName;

  public String getFirstName(){
  return mFirstName;

   public String getLastName(){
  return mLastName;

public class Forum {
  private String mTopic;

  public String getTopic() {
      return mTopic;

  public Forum(String topic){
  mTopic =topic;

  public void addPost(ForumPost post) {

      System.out.printf("New post from %s %s about %s.\n",

public class Example {

  public static void main(String[] args) {
    System.out.println("Starting forum example...");
    if (args.length < 2) {
       System.out.println("first and last name are required. eg:  java Example Craig Dennis");
    Forum forum = new Forum("Java");
    // Take the first two elements passed args
    User author = new User("Craig","Dennis");
    // Add the author, title and description
    ForumPost post = new ForumPost(author,"java","amazing");
