278 PointsWhy is there a data type name "private User author;"?
I don't understand if "private User author" is accepting String or what? Please Help! Thanks.
public class Forum {
private String mTopic;
public Forum(String topic){
mTopic = topic;
}
public Forum(String topic){
mTopic = topic;
}
// TODO: add a constructor that accepts a topic and sets the private field topic
public String getTopic() {
return topic;
}
/* Uncomment this when you are prompted to do so
public void addPost(ForumPost post) {
System.out.printf("A new post in %s topic from %s %s about %s is available",
topic,
post.getAuthor().getFirstName(),
post.getAuthor().getLastName(),
post.getTitle()
);
}

public class User {
private String firstName;
private String lastName;
// TODO: add private fields for firstName and lastName
public User(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;

6,455 PointsIf you are not about the data type, refer to the class and see what the constructor fields are
public User(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
As you can see here User takes two strings, one for the first name and one for the last name.
