Question

I have reviewed my code several times, and even looked at solutions to this, however I don't see any errors. Please help

Forum.java

public class Forum {
  private String topic;

  public setTopic(String topic){
    this.topic = topic;
  }

  public String getTopic() {
    return topic;
  }



}

User.java

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;
  }

}

ForumPost.java

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;
  }
}

Main.java

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);
    }
}

There 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 named addPost 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.
