Is this Tutorial for You?

Do you know what will happen when you try to compile/run this code in Java 5?

import java.util.*;
public class Conference {
  private Collection delegates = new ArrayList();
  public void add(String... names) {
    Collections.addAll(delegates, names);
  }
  public void removeFirst() {
    delegates.remove(0);
  }
  public String toString() {
    return "Conference " + delegates;
  }
  public static void main(String[] args) {
    Conference sun_tech_days = new Conference();
    sun_tech_days.add("Herman", "Bobby", "Robert");
    sun_tech_days.removeFirst();
    System.out.println(sun_tech_days);
  }
}

1. I give up.
2. Code fails to compile.
3. Runtime exception.
4. Output: Conference [Bobby, Robert]
5. Output: Conference [[Ljava.lang.String;@86498]
6. Output: Conference [Herman, Bobby, Robert]
