I am completely stuck on this lesson

I do not know what this lesson wants me to do, i keep seeing an error saying "I expected to see the names i passed in the args, hmm."

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) {
    mFirstName = firstName;
    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) {

      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("Gabriel Llanes");
     Forum forum = new Forum("Java");
    // Take the first two elements passed args
    User author = new User("Gabriel", "Llanes");
    // Add the author, title and description
    ForumPost post = new ForumPost(author, "Java", "It feels great");

The comment actually gives you the answer :)

// Take the first two elements passed args
    User author = new User("Gabriel", "Llanes");

So write this instead:

// Take the first two elements passed args
    User author = new User(args[0], args[1]);
