This is for the final challenge in the last Java Objects stage.
public class ForumPost {
private User mAuthor;
private String mTitle;
private String mDescription;
public User getAuthor() {
return mAuthor;
}
public String getTitle() {
return mTitle;
}
// 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 class Forum {
private String mTopic;
public Forum(String topic) {
mTopic = topic;
}
public String getTopic() {
return mTopic;
}
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);
}
}

7,786 PointsFor task 2, it says also add getters in User.Java
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;
}
//here are the two getters which just return the member fields
public String getFirstName() {
return mFirstName;
}
public String getLastName() {
return mLastName;
}
}
This is task 3, ForumPost.Java
public class ForumPost {
private User mAuthor;
private String mTitle;
private String mDescription;
//make the constructor
public ForumPost(User author,String title,String description) {
mAuthor = author;
mTitle = title;
mDescription = description;
}
public User getAuthor() {
return mAuthor;
}
public String getTitle() {
return mTitle;
}
//Add description getter so return decription member field using method
public String getDescription() {
return mDescription;
}
// TODO: We need to expose the description
}
Uncomment stuff in forum.java
public class Forum {
private String mTopic;
public Forum(String topic) {
mTopic = topic;
}
public String getTopic() {
return mTopic;
}
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());
}
}
Last part is in Example.Java
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");
}
//This is what you uncomment and follow the comments below to fill in the parameters which i have done already.
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","fixed it");
forum.addPost(post);
}
}
