Expected to see names passed through args

I am not sure what names are supposed to show. Please help!

ForumPost.java
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;
  }

  // TODO: We need to expose the description
}
User.java
public class User {
    private String mFirstName;
  private String mLastName;

  public User(String firstName, String lastName) {
    mFirstName = firstName;
    mLastName = lastName;// TODO:  Set the private fields here
  }
public String getFirstName(){
return mFirstName;
}
public String getLastName(){
return mLastName;
}
}
Forum.java
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 %s.\n",
                         post.getAuthor().getFirstName(),
                         post.getAuthor().getLastName(),
                         post.getTitle(), post.getDescription());

  }
}
Example.java
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("Michelle", "Pak");
    // Add the author, title and description
     ForumPost post = new ForumPost(author, "FINISHED","excited");
     forum.addPost(post);
  }
}

Hi Michelle,

In this challenge, the args passed into main are used to hold the values of the author names. So, args[0] is passed in for the firstName and args[1] holds the expected value for lastName.

To access this, change your use of the User constructor to use those two args rather than the strings you have used:

User author = new User(args[0], args[1]);

I hope that helps!

Steve.

Thank you!
