::SOLVED:: User author

::SOLVED::

The issue I'm having is that I'm unsure of how to pass the User author to the ForumPost creation. Can anyone provide guidance? First time posting a question, so I'm sure I'm not adding the challenge information correctly so let me know if you need more info!

I've tried:

  1. manually inputting Strings
  2. attempting to use just author
  3. various other permutations of the above

Any assistance or direction would be great :)

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 String getDescription() {
    return mDescription;
  }

  public User getAuthor() {
    return mAuthor;
  }

  public String getTitle() {
    return mTitle;
  }

  // TODO: We need to expose the description
}
User.java 
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;
  }
}
Forum.java 
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());

  }
}
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("Jesse", "James");
    // Add the author, title and description
    ForumPost post = new ForumPost(, "Yay", "Finally done");
     forum.addPost(post);
  }
}

And I removed my previous tries from the Example.java User author portion of the ForumPost, for clarity's sake.

Figured it out:

I needed to pass the args instead of passing an actual String. Duh.

Note to self: go re-review the args video again
