In User.java I got this message: Bummer! java.lang.IllegalArgumentException: ParseException: com.github.javaparser.ParseException: Encountered " ";" "; "" at line 3, column 20.

A couple of points here.
In Forum.java
you have declared topic
a second time. Delete the line as indicated below:
public class Forum {
private String topic; // already declared here
// TODO: add a constructor that accepts a topic and sets the private field topic
String topic; // <- so delete this
public Forum(String topic){
this.topic = topic;
}
Next, in User.java
you haven't added a data type of firstName
or lastName
. They are strings, so amend you code to:
private String firstName;
private String lastName;
Your constructor for User
looks fine but you haven't added the getters and setters helper methods correctly. I'll do them for firstName
- you'll need to do lastName
:
public String getFirstName(){
return firstName;
}
public void setFirstName(String firstName){
this.firstName = firstName;
}
I think that should sort your issues out and let you carry on with the rest of the challenge.
Steve.
