Question: Alright so now let's focus on ForumPost. It's going to need a constructor that takes a User author a String title and a String description. Don't forget to initialize the member fields in the constructor. Also please add the getter for mDescription.
Code:
public class ForumPost {
private User mAuthor;
private String mTitle;
private String mDescription;
public FormPost(User author, String title, String description) {
mAuthor = author;
mTitle = title;
mDescription = description;
}
public User getAuthor() {
return mAuthor;
}
public String getTitle() {
return mTitle;
}
public String getDescription() {
return mDescription;
}
// TODO: We need to expose the description
}
public class User {
private String mFirstName;
private String mLastName;
public User(String firstName, String lastName) {
// TODO: Set the private fields here
mFirstName = firstName;
mLastName = lastName;
}
public String getFirstName(){
return mFirstName;
}
public String getLastName(){
return mLastName;
}
}
public class Forum {
private String mTopic;
public String getTopic() {
return mTopic;
}
public Forum(String topic) {
//set mTopic to the topic passed in to the constructor
mTopic = topic;
}
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 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);
}
}

10,300 Pointsyou were very close ...change the spelling from FormPost on the public to ForumPost. and it should be like this: public class ForumPost { private User mAuthor; private String mTitle; private String mDescription;
public ForumPost (User author, String title, String description) { mAuthor = author; mTitle = title; mDescription = description; }
public User getAuthor() { return mAuthor; }
public String getTitle() { return mTitle; }
public String getDescription() { return mDescription; } // TODO: We need to expose the description }
