Author, type User; is formed of 2 strings: firstName and lastName.. How do I pass the author?
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) {
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() {

}
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("Ilies", "Mihai");
// Add the author, title and description
ForumPost post = new ForumPost(author, "Java", "It`s greate to learn!");
forum.addPost(post);
}

Java Web Development Techdegree Graduate 22,175 PointsHi, You did everything correct, except smallest thing.
Craig wants you to read first and last name through arguments:
So change this:
// Take the first two elements passed args
// you created your own "Ilies" and "Mihi"
//but you should pass here args[0], args[1]
// User author = new User("Ilies", "Mihai");
User author = new User(args[0], args[1]);
Do you understand how does it work know?
When you run :
javac Example.java && java Example
It will print you:
first and last name are required. eg: java Example Craig Dennis
Because you need to provide arguments, like
javac Example.java && java Example Craig Dennis
It will print you
New post from Craig Dennis about Java.
In case of your code you hard-coded, author's name ....
