/* Uncomment this when prompted
Forum forum = new Forum("Java");
// TODO: pass in the first name and last name that are in the args parameter
User author = new User();

16,646 PointsI think you might have been confused by the first task, so let me walk you through it. The task is this: Add a constructor that accepts a String named topic to Forum.java. Initialize the private field topic in the constructor to the value passed in.
Your Forum.java should look like this:
public class Forum {
private String topic;
//-----> This is the new constructor
private Forum(String topic) {
this.topic = topic;
}
//-----> end constructor
public String getTopic() {
return topic;
}
/* Uncomment this when you are prompted to do so
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()
);
}
*/
}
See if that helps to get you on the right path. If not, feel free to ask more questions or review the video(s) that came before the challenge. Don't give up!
