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("John", "Brown");
ForumPost post = new ForumPost(author,"NewStart","BecomeProgrammer");

A few things, make sure you uncommented the code in Forum. Also, the author object needs to be created by using the values passed in args like so:

Forum forum = new Forum("Java");
    // TODO: pass in the first name and last name that are in the args parameter
    User author = new User(args[0], args[1]);
    // TODO: initialize the forum post with the user created above and a title and description of your choice
    ForumPost post = new ForumPost(author, "test", "test");
    forum.addPost(post);
