i have to add a private field to store the parameters defined in the constructor and add the appropriate getter

Question

i completely forgot whats a getter :/

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) {
    // 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) {
      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);
  }
}

A getter is just a public method of a class that returns a private member variable. It looks like your question is about Task 2 so for this task since there are two private member variables we need two getters:

public class User {
    private String mFirstName;
    private String mLastName;

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

    public String getFirstName() {
        return mFirstName;
    }

     public String getLastName() {
        return mLastName;
    }
}
