Help!! Error message to make sure I have uncommented code that I have already uncommented.

My preview screen is showing no errors, but I am not able to go forward because I'm getting an error to uncomment the code. I tried to uncomment everything and it just gave me more errors, so I deleted all the comments and it is still not allowing me to go forward. Am I missing something?

Forum.java 
public class Forum {
  private String topic;

  public Forum(String topic) {
   this.topic = topic;
  }



  public String getTopic() {
    return topic;
  }



  public void addPost(ForumPost post) {
    System.out.printf("A new post in %s topic from %s %s about %s is available",
            topic,
            post.getAuthor().getFirstName(),
            post.getAuthor().getLastName(),
            post.getTitle()
    );
  }
}
User.java 
public class User {
  // TODO: add private fields for firstName and lastName
  private String firstName;
  private String lastName;

  public void setFirstName() {
      firstName = this.firstName;
    }
  public void setLastName() {
      lastName = this.lastName;
    }

  public User(String firstName, String lastName) {

    this.firstName = firstName;
    this.lastName = lastName;

  }


  public String getFirstName() {
    return this.firstName;
  }
  public String getLastName() {
    return this.lastName;  
  }

}
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;
  }
}
Main.java 
public class Main {

  public static void main(String[] args) {
    System.out.println("Beginning forum example");
    if (args.length < 2) {
      System.out.println("Usage: java Main <first name> <last name>");
      System.err.println("<first name> and <last name> are required");
      System.exit(1);
    }

    Forum forum = new Forum("Java");

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

    ForumPost post = new ForumPost(author, "This is the forumPost title", 
                                   "This is the forum post description");




  }
