What is wrong with my code?

mAuthor = author;
mTitle = title;
mDescription = description;

return mTitle;
}

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

public class Example {
public static void main(String[] args) {

}
Forum forum = new Forum("Java");
// Take the first two elements passed args
User author = new User("david","gray");
// Add the author, title and description
ForumPost post = new ForumPost(author,"happy to complete","java course");
forum.addPost(post);
}

User author = new User(args[0], args[1]);
I think they're trying to get you to recognize the String[] args in the main method can actually be used to hold arrays. In this example, the if statement at the top tells us there is a first and last name saved.
