Java Objects - Wrapping Up - Challenge Task 4of4

Im receiving the following failure:

Bummer! I expected to see the names I passed in through the args, but I do not. Hmm.

But...judging from the output, it looks like my code is correct:

Starting forum example...
New post from Tim Boland about Teamtreehouse Java Course.

Here is my code below:

ForumPost.java

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

  public ForumPost(User author, String title, String description) {
    this.mAuthor = author;
    this.mTitle = title;
    this.mDescription = description;
  }

  public User getAuthor() {
    return mAuthor;
  }

  public String getTitle() {
    return mTitle;
  }

  public String getDescription() {
    return mDescription;
  }
}

User.java

public class User {
  private String mFirstName;
  private String mLastName;

  public User(String firstName, String lastName) {
    // TODO:  Set the private fields here
    this.mFirstName = firstName;
    this.mLastName = lastName;
  }

  public String getFirstName() {
    return mFirstName;
  }

  public String getLastName() {
    return mLastName;
  }
}

Forum.java

public class Forum {
  private String mTopic;

  public Forum(String topic) {
    this.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(),
                         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("Tim", "Boland");
    // Add the author, title and description
     ForumPost post = new ForumPost(author, "Teamtreehouse Java Course", "This is my favorite course");
     forum.addPost(post);
  }
}

Hi Timothy,

Could you share your code? The challenge asks to pass the first name and last name from arguments.

Thanks,

Code shared...i cant figure out what Im missing

Same boat and I too confirmed in workspaces that it outputs the user name.

Just solved it. Great explanation at https://teamtreehouse.com/community/output-is-appropriate-in-editor-but-still-fails-challenge

I had to rewatch the array video and then reread the error code. I then realized he had already put in a name in args[0] and args[1] and simply wanted us to output the name that HE had entered into args.

The only change you need is

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