Wrapping Up Challenge: Task 2 of 4 - issue with names

Is it really necessary to name private variables 'firstName' and 'lastName'? I get this error when I attempt to use format 'mFirstName' and 'mLastName'. I got to Task 4 / 4 and get an error saying task 2 is no passing. Really confused now thinking I will need to rework everything. What am I doing wrong really? Spent around an hour on the forum and see everyone is doing just fine using 'mFirstName' sort of thing.

Bummer! Make sure you add a private String field to the User class named firstName

Forum.java 
public class Forum {
  private String topic;
  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",
                         post.getAuthor().getFirstName(),
                         post.getAuthor().getLastName(),
                         post.getTitle());

  }
}
User.java 
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;
   }
}
ForumPost.java 
public class ForumPost {
  private User mAuthor;
  private String mTitle;
  private String mDescription;

  public User getAuthor() {
    return mAuthor;
  }

  public String getTitle() {
    return mTitle;
  }

  // TODO: We need to expose the description
Main.java 
public class Main {

  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");
    User author = new User(args[0], args[1]);
    ForumPost post = new ForumPost(author, "Java Is Cool", "Wahoo!");
    forum.addPost(post);
  }

}
