[SOLVED] What's wrong with my setter?

I thought this would be the correct way to complete this challenge:

public void setTopic(String topic) { mTopic = topic; }

ForumPost.java
public class ForumPost {
  private User mAuthor;
  private String mTitle;
  private String mDescription;

  public User getAuthor() {
    return mAuthor;
  }

  public String getTitle() {
    return mTitle;
  }

  // TODO: We need to expose the description
}
User.java
public class User {

  public User(String firstName, String lastName) {
    // TODO:  Set the private fields here
  }
}
Forum.java
public class Forum {
  private String mTopic;

  public String getTopic() {
      return mTopic;
  }

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

 public void setTopic(String topic) {
       mTopic = topic;
    }

}
Example.java
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();
    // Add the author, title and description
    // ForumPost post = new ForumPost();
    // forum.addPost(post);
  }
}

When I go the the challenge the first task is to add a constructor to the forum class, that sets the value of mTopic.

The setter you have will compile and run just fine but it it not a constructor. All you need to do is change the setTopic method to a constructor and it should pass.

Jonathan Petersen, sorry but what do you mean by change the setTopic method to a constructor?

Okay I've figured it out!

public Forum(String topic) { mTopic = topic; }

Thanks :)
