I've tried all that I've learned so far to rectify this situation but I'm at an impasse. Here is my code:
public class Example { private ForumPost post; private Forum forum; private User author;
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");
} else {
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, "Winning", "I crushed this.");
forum.addPost(post);
}
}
}
and here is the output: Starting forum example... New post from User@4aa298b7 Winning I crushed this.
here is the workspace feed back. "I expected the namesI gave to the args. did not see them. hmm."
I obviously didn't crush it. If you see an issue please point me in the right direction. Thanks to kind soul who helps me discover my error.
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
}
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) {
// When all is ready uncomment this...
System.out.printf("New post from %s %s about %s.\n",
post.getAuthor(),
post.getTitle(),
post.getDescription());
}
}
public class Example {
private ForumPost post;
private Forum forum;
private User author;
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("Damion", args[1]);
// Add the author, title and description
ForumPost post = new ForumPost(author, "Winning", "I crushed this.");
forum.addPost(post);
}
}

71,830 PointsOne small issue. They wanted you to use args for both first and last name:
User author = new User(args[0], args[1]);
// Add the author, title and description
ForumPost post = new ForumPost(author, "Winning", "I crushed this.");

iOS Development Techdegree Student 5,594 Pointsthis line - User author = new User("Damion", args[1]); is actually - User author = new User(args[0], args[1]); I was trying permutations of everything to try and figure out the issue.
