2,204 PointsIm not quite sure what this is asking me to do.
It just says to do what the comments say but I do not understand what it is asking.
public class Forum {
private String topic;
// TODO: add a constructor that accepts a topic and sets the private field topic
public Forum(String topic) {
topic = this.topic;
}
public String getTopic() {
return topic;
}
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 {
// TODO: add private fields for firstName and lastName
private String firstName, lastName, name;
public User(String firstName, String lastName) {
firstName = this.firstName;
lastName = this.lastName;
}
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
}
public class ForumPost {
private User author;
private String title;
private String description;
public ForumPost(User author, String title, String description) {
author = this.author;
title = this.title;
description = this.description;
}
public User getAuthor() {
return author;
}
public String getTitle() {
return title;
}
public String getDescription() {
return description;
}
}
public class Main {
public static void main(String[] args) {
System.out.println("Beginning forum example");
if (args.length < 2) {
System.out.println("Usage: java Main <first name> <last name>");
System.err.println("<first name> and <last name> are required");
System.exit(1);
}
Forum forum = new Forum("Java");
// TODO: pass in the first name and last name that are in the args parameter
User author = new User();
// TODO: initialize the forum post with the user created above and a title and description of your choice
ForumPost post = new ForumPost(author, forum, );
forum.addPost(post);
}
}

constructor should look like this:
public Forum(String topic) {
this.topic = topic;
}
Fix all of them in a similar way.
Also, in the Main
class when creating a new user
you need to pass in a first name and a last name. Those you can get from the args
array. args[0]
would be the first name and args[1]
the last name.
Finally, in the Main
class when creating a ForumPost
you need to pass in a description as the third argument.
