Hi guys, i am stuck in here, can someone please send the code? Thanks!

Update the DummyItem constructor to set the new 'director' member variable to a third parameter also named ‘director’. Then go back and add director last names to the items. Bonus points if you use the correct directors for the movie!

DummyContent.java 
public class DummyContent {

    public static List<DummyItem> ITEMS = new ArrayList<DummyItem>();
    public static Map<String, DummyItem> ITEM_MAP = new HashMap<String, DummyItem>();

    static {
        // Add 3 sample items.
        addItem(new DummyItem("1", "The Avengers", "Whedon 1"));
        addItem(new DummyItem("2", "The Hobbit", "Jackson 2"));
        addItem(new DummyItem("3", "Ball of Fire", "Hawks 3"));
    }

    private static void addItem(DummyItem item) {
        ITEMS.add(item);
        ITEM_MAP.put(item.id, item);
    }

    /**
     * A dummy item representing a piece of content.
     */
    public static class DummyItem {
        public String id;
        public String content;
        public String director;

        public DummyItem(String id, String content, String director) {
            this.id = id;
            this.content = content;
            this.director= director;
        }
    }
}

The only thing I can see different is the lack of space in your constructor assignment to director.

This code passes:

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class DummyContent {

    public static List<DummyItem> ITEMS = new ArrayList<DummyItem>();
    public static Map<String, DummyItem> ITEM_MAP = new HashMap<String, DummyItem>();

    static {
        // Add 3 sample items.
        addItem(new DummyItem("1", "The Avengers", "Dave"));
        addItem(new DummyItem("2", "The Hobbit", "Steve"));
        addItem(new DummyItem("3", "Ball of Fire", "Brian"));
    }

    private static void addItem(DummyItem item) {
        ITEMS.add(item);
        ITEM_MAP.put(item.id, item);
    }

    /**
     * A dummy item representing a piece of content.
     */
    public static class DummyItem {
        public String id;
        public String content;
        public String director;

        public DummyItem(String id, String content, String director) {
            this.id = id;
            this.content = content;
            this.director = director;
        }
    }
}
