After you uncomment the code in Main.java and Forum.java, fix the code as described in the comments of Main.java. The code in main is attempting to use the code you just fixed.
I don't get what I am supposed to do. Help!?
public class Forum {
private String topic;
// TODO: add a constructor that accepts a topic and sets the private field topic
public topic(String topic){
this.topic = 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;
private String lastName;
public User(String firstName, String lastName) {
// TODO: set and add the private fields
this.firstName = firstName;
this.lastName = lastName;
}
public String getFirstName(){
return firstName;
}
public String getLastName(){
return lastName;
}
// TODO: add getters for firstName and lastName
}
public class ForumPost {
private User author;
private String title;
private String description;
// TODO: add a constructor that accepts the author, title and description
public ForumPost(User author, String title, String description){
this.author = author;
this.title = title;
this.description = 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();
forum.addPost(post);
}
}

Front End Web Development Techdegree Graduate 84,738 Points- You need to pass in the firstName and lastName arguments when you create the new User. These should come from the args array that gets passed into the main method.
- You'll need to pass in that user object as well as a title and description when you create the new ForumPost.
- There's also a problem back in Forum.java - your constructor method isn't named correctly
Let me know if you need any more pointers.
