Once again can someone please help I am stuck on task 2 of 2. Java project. 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!

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", "Directors name1"));

    addItem(new DummyItem("2", "The Hobbit", "Directors name2"));

    addItem(new DummyItem("3", "Ball of Fire", "Directors name3"));   

private static void addItem(DummyItem 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) {
        this.id = id;
        this.content = content;
        this.director = director;

Check the parameters of the DummyItem "constructor" within the DummyItem class. The line "this.director = director;" is not being told how to find ".director"...

Ok so this.director = director; needs to find the string director? how can I do this?

I got it thanks!!

public DummyItem(String id, String content, String director) {

    this.id = id;

    this.content = content;

    this.director = director;
