935 PointsI cant find the errors
I keep looking at the forums and answers but I cant get to get it right. Could someone help me with this code. Thanks
public class Forum {
private String topic;
// TODO: add a constructor that accepts a topic and sets the private field topic
public String (String topic) {
topic = topic;
}
public String getTopic() {
return topic;
}
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
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() {
return firstName;
}
// TODO: add getters for firstName and lastName
public String getLastName() {
return lastName;
}
}
public class ForumPost {
public ForumPost(User author, String title, String description) {
this.author = author;
this.title = title;
this.description = 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);
}
Forum forum = new Forum("Java");
String firstName = args [0];
String lastName = args [1];
// TODO: pass in the first name and last name that are in the args parameter
User author = new User(firstName, lastName);
// TODO: initialize the forum post with the user created above and a title and description of your choice
ForumPost post = new ForumPost(author, "Awesome", "class");
forum.addPost(post);
}
}

16,481 PointsThat seems like it should work. I wonder if the script checking the code challenge isn't quite flexible enough. I was able to get it to pass by using the args
elements directly as parameters to the User
constructor, like so:
User author = new User(args[0], args[1]);
If that doesn't work for you, what errors are you getting?

935 PointsThanks, I tried that and nothing, but then I added private strings to forumPost.java and it did the trick! Thanks so much for your help though!

16,481 PointsOh, yeah, that'd do it. Nice debugging!
