Bummer! 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

In the Forum.java
file you have changed the name of the topic
field variable to mTopic
and changed the message that is printed when the addPost
method is called. Those changes are enough to mess up the challenge checker.
If you change the name back and restore the original addPost
message like this:
public class Forum {
private String topic;
public String getTopic() {
return topic;
}
public Forum(String topic){
this.topic = topic;
}
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()
);
}
}
Then your code will be accepted.
