Not sure what this code challenge is asking?

It seems so obvious but not sure what is missing?

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 User getAuthor() { return mAuthor; }

public String getTitle() { return mTitle; }

public String getDescription() { return mDescription; 
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 void addPost(ForumPost post) {
       When all is ready uncomment this...
      System.out.printf("New post from %s %s about %s.\n",

  public Forum(String topic) {
   mTopic = topic;
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();
     Add the author, title and description
     ForumPost post = new ForumPost();

Did you do the comments in Example.java? Looks like you uncommented the actual comments.

Thanks it was my Example.java and here was I got and it passed :D

Forum forum = new Forum("Java"); // Take the first two elements passed args User author = new User(args[0],args[1]); // Add the author, title and description ForumPost post = new ForumPost(author, "DSF", "DSFA"); forum.addPost(post);
