I expected to see names I passed in through args but I do not.

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

  public ForumPost(User userAuthor, String title, String description){

    this.mAuthor=userAuthor;
    this.mTitle=title;
    this.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) {
    this.mFirstName=firstName;
    this.mLastName=lastName;
    }
   public String getFirstName(){
    return mFirstName;
    }
    public String getLastName(){
    return mLastName;
    } 
}

public class Forum {
  private String mTopic;

  public Forum(String topic){
  mTopic=topic;
  }
  public String getTopic() {
      return mTopic;
  }

  public void addPost(ForumPost post) {
      // When all is ready uncomment this...
      System.out.printf("New post from %s %s about %s.\n",
                         post.getAuthor().getFirstName(),
                         post.getAuthor().getLastName(),
                         post.getTitle());

  }
}

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("Asser", "Moussa");
     //Add the author, title and description
     ForumPost post = new ForumPost( author ,"Kotla fel Fara3","Book");
     forum.addPost(post);
  }
}
