Stuck on the last thing...ready to ram head into wall

ForumPost.java

  // TODO: We need to expose the description

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

In the Example class, in the user constructor, the instruction tells you to use the passed in args. In the ForumPost constructor, you need to use the object of type "User" as your first and then for the other two, the instructions tells you to describe how it feels like to program in Java as below. if the answer helps please click on best answer and if it doesnt give me a shout

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(args[0],args[1]);
    // Add the author, title and description
   ForumPost post = new ForumPost(author, "Wow at Last", "Java is Awesome");
    forum.addPost(post);
  }
}

After doing what Blessing Kabasa suggests, you still won't have solved the Challenge. Your problem lies in the following code:

  public void addPost(ForumPost post) {
      /* When all is ready uncomment this...*/
     System.out.printf("New post from %s %s about %s.\n",
                       ForumPost.getAuthor().getFirstName(),
                      ForumPost.getAuthor().getLastName(),
                     ForumPost.getTitle());

  }

Replace ForumPost with post three times in your System.out.printf
