Don't know what to do

Cant get my head around this exercise

ForumPost.java 
public class ForumPost {
  private User mAuthor;
  private String mTitle;
  private String mDescription;

  public User getAuthor() {
    return mAuthor;
  }

  public String getTitle() {
    return mTitle;
  }

  // TODO: We need to expose the description
}
User.java 
public class User {


  public User(String firstName, String lastName) {
    mAuthor = firstName + lastName;
    // TODO:  Set the private fields here
  }

}
Forum.java 
public class Forum {
  private String mTopic;

  public String getTopic() {
      return mTopic;
  }

  public Forum (String topic) {
    mTopic = topic;
  }


  public void addPost(ForumPost post) {
      /* When all is ready uncomment this...
      System.out.printf("New post from %s %s about %s.\n",
                         post.getAuthor().getFirstName(),
                         post.getAuthor().getLastName(),
                         post.getTitle());
      */
  }
}
Example.java 
public class Example {

  public static void main(String[] args) {
    System.out.println("Starting forum example...");
    if (args.length < 2) {
       System.out.println("first and last name are required. eg:  java Example Craig Dennis");
    }
    // Forum forum = new Forum("Java");
    // Take the first two elements passed args
    // User author = new User();
    // Add the author, title and description
    // ForumPost post = new ForumPost();
    // forum.addPost(post);
  }
}

Dear Alex,

In 2d part of this assignment you should work only with User class. I'm not sure what version of "Java - Objects" you are following, but in the latest the tasks are following:

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

}

Here is the solution:

public class User {
    // TODO: set private fields
    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() {
        // TODO: add getters for firstName and lastName
        return firstName;
    }

    public String getLastName() {
        // TODO: add getters for firstName and lastName
        return lastName;

    }

}
