Constructor field First Name of the User Class I put the First Name in the Constructor field as well as the last name.

The code wants me to put the first name constructor in the user class. I believe I already did that in the Constructor. I don't know what else need to be done to get though Challenge Task 2 of 4. Thanks for help in advance.

Forum.java
public class Forum {
  private String topic;

  // TODO: add a constructor that accepts a topic and sets the private field topic

  public Forum(String topic){
  this.topic = 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()
    );
  }
  */

}
User.java
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.fistName =  fistName; 
   this.lastName =  lastName;
  }

  // TODO: add getters for firstName and 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;

  // TODO: add a constructor that accepts the author, title and 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);
    }
    /* Uncomment this when prompted
    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);

// */
  }

Hi there, Willard! You just have two typos and two capitalization errors.

You typed this:

this.fistName =  fistName; 

But that should be:

this.firstName =  firstName; 

Note the difference between "fist" and "first".

Secondly when we "camel case" our getters and setters, the word immediately after the "get" and "set" part should be capitalized. So that should be getFirstName and getLastName. Check your capitalization on these.

Hope this helps! :sparkles:

Thanks I though I was missing a full step with the challenge.
