3,676 PointsNot 100% sure what I am missing. It says "Looks like task 2 no longer passes" but when I go back, task 2 passes.
I go back to task 2 and without changing anything it passes just fine. Same with task 3. Any help would be appreciated.

private String mTopic;

2)private String firstName; private String lastName;
this.firstName = firstName; this.lastName = lastName;
public String getFirstName() { return firstName; }
public String getLastName() { return lastName; }
3) public ForumPost (User author, String title, String description ) { this.author = author; this.title = title; this.description = description; }
4) Forum forum = new Forum("Java"); User author = new User(args[0], args[1]); ForumPost post = new ForumPost(author, "new title", "no description"); forum.addPost(post);
Just check it out one more, I think the problem is you user mFirstName instead of firstName, but in the task , firstName is what they really want

3,676 PointsThank you. Went back and looked at the variables. Changed them all to "this.var = var" and that seemed to do the trick.
