1,089 PointsHi,
The error appears at Main.Java section. It's saying remember to use args[0] for first name and args [1] for the surname.

5,520 PointsThe error message also confused me at first, your mistake is in User you have to turn over the values in the constructor.
public class User {
private String firstName;
private String lastName;
public User(String firstName, String lastName) {
// TODO: Set the private fields here
this.firstName = firstName;
this.lastName = lastName;
}
I hope I could help you
