2,560 PointsJava uncomment
Not sure what I am doing wrong here: Finally, uncomment the addPost method in Forum.java. Then for the last task, uncomment the main method in Example.javafixing the bugs as you go to use the new working code. For the forum post title and description, use that to shout out about how it feels to complete this challenge.
PS. You're amazing.
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;
}
// TODO: We need to expose the description
public String getDescription() {
return mDescription;
}
}
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 Forum(String topic) {
mTopic = topic;
}
public String getTopic() {
return mTopic;
}
public void addPost(ForumPost post) {
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);
}
}

23,733 PointsThe User constructor expects two arguments, a first name and a last name. These should come from the args array. The first element of the array, args[0], is the first name passed in and the second element, args[1], is the last name. Also, the ForumPost constructor expects three arguments, an author, a title, and a description. Try this:
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(args[0], args[1]);
// Add the author, title and description
ForumPost post = new ForumPost(author, "Java Objects Last Challenge", "It feels awesome to finsh the challenge!");
forum.addPost(post);
}
}
