5,066 PointsBummer! Are you sure you used the arguments passed in from the main method in Main.java? args[0] is the firstName and args[1] should be the last name. 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, "title", "description");
forum.addPost(post);
}

5,430 PointsForum forum = new Forum("Java"); User author = new User(args[0], args[1]); ForumPost post = new ForumPost(author, "title", "description"); forum.addPost(post);
and you miss topic at add post method in main.java :D
