5,749 Points//Looking at your code on {ForumPost.java} your constructor is private Forum but the Class is ForumPost, thats the first mistake.2. still under that you wrote mTitle = tile, second mistake.
my advice will be "Can you please try to use the [this] KeyWord on your constructors...
public ForumPost(User author, String title){ this.author = author; this.title = title; ..... }"
// TODO: pass in the first name and last name that are in the args parameter
String firstName = args[0];
String lastName = args[1];
User author = new User(firstName, lastName);
// TODO: initialize the forum post with the user created above and a title and description of your choice
ForumPost post = new ForumPost(author, "Programming is Good", "It teaches how to create new things");
forum.addPost(post);
