What did I do wrong and how do I fix it

Forum.java
public class User {
  // Private fields to store firstName and lastName
  private String firstName;
  private String lastName;

  // Constructor to initialize firstName and lastName
  public User(String firstName, String lastName) {
    this.firstName = firstName;
    this.lastName = lastName;

     // Constructor that accepts a topic and sets the private field topic
  public User(String topic) {
    this.topic = topic;
  }

  // Public getter for topic  
    public String gettopic(){
    return topic;  
  }  

  // Public getter for firstName
  public String getFirstName() {
    return firstName;
  }

  // Public getter for lastName
  public String getLastName() {
    return lastName;
  }
}
User.java
public class User {
  // TODO: add private fields for firstName and lastName

  public User(String firstName, String lastName) {
    // TODO: set and add the private fields

  }

  // TODO: add getters for firstName and lastName

}
ForumPost.java
public class ForumPost {
  private User author;

      System.err.println("<first name> and <last name> are required");
      System.exit(1);

It looks like you might be working on task 2, which the instructions say should be done "In User.java…"

But it looks like the code was added to Forum.java instead.   :see_no_evil:
