750 PointsAfter you uncomment the code in Main.java and Forum.java, fix the code as described in the comments of Main.java. The co
I have reviewed my code several times, and even looked at solutions to this, however I don't see any errors. Please help
public class Forum {
private String topic;
public setTopic(String topic){
this.topic = topic;
}
public String getTopic() {
return topic;
}
}
public class User {
private String firstName;
private String lastName;
public User(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = 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){
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");
User author = new User(args[0],args[1]);
ForumPost post = new ForumPost(author, "The Code", "The fastest code ever.");
forum.addPost(post);
}
}

28,558 PointsThere are two issues:
In task 1 you are asked to add a constructor, constructors have to be named exactly the same thing as the class they are inside of, you have named it
setTopic
which is incorrect.The
Forum.java
file is meant to contain a commented out method namedaddPost
which you are meant to uncomment at the end, but you have removed that method entirely from your solution.
If you fix those two issues by replacing the code in the Forum.java
file with this:
public class Forum {
private String topic;
public Forum(String topic){ // Constructor renamed from setTopic to Forum
this.topic = topic;
}
public String getTopic() {
return topic;
}
public void addPost(ForumPost post) { // This method was missing from your code
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()
);
}
}
Then your code will work.

750 PointsOh! I think I accidentally got confused between the constructor and the method for that task. And yea, I was wondering why there was an addPost method in the main, if it wasn't in my Forum class. Thank you very much!! I really appreciate it!
