I cant work my head around this, been at it for a good part of yesterday to present. How do i get past it
public class Forum {
private String topic;
// TODO: add a constructor that accepts a topic and sets the private field 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()
);
}
*/
}
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
}
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;
}
}
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);
// */
}

public class Forum {
//private field
private String topic;
//CONSTRUCTOR for Forum looks like this. It sets the above private field.
public Forum(String topic){
this.topic = topic;
}
//the setter does not need to return anything because it only resets the private field so the value so it is void.
public void setTopic(String topic){
this.topic = topic;
}
//getter returns the private field
public String getTopic(){
return this.topic:
}
This is not exactly everything in the code challenge but I hope it helps. Let me know if you are still having problems and I will come back.
