28,558 PointsYou did more than just uncomment the code, you removed parts of the code and also modified some code you were not supposed to.
In Forum.java
the commented code was this:
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()
);
}
Which you have removed entirely from the file.
In Main.java
you changed the name of the ForumPost
object from being called post
to being called ForumPost
which is an invalid name since it is the same as the class name.
You also removed this line forum.addPost(post);
from the Main.java
file.
If you change the Forum.java
file to look exactly like this:
public class Forum {
private String topic;
public Forum(String topic){
this.topic = topic; // <--- same here :)
}
public String getTopic() {
return topic;
}
// Added this function which had been removed
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()
);
}
}
And the Main.java
file to look exactly like this:
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];
User author = new User(firstName, lastName);
// Changed object name from ForumPost to post
ForumPost post = new ForumPost(author, "Programming is awesome", "Cuz it makes us create new stuff");
// Added this line which had been removed
forum.addPost(post);
}
}
Then your code will work.
