``` package BlackJack; import java.util.LinkedList; import java.util.List; import java.util.regex.Pattern; public class Deck { private List<Card> cards; Deck() { this.cards = generateCards(); } private List<Card> generateCards() { LinkedList<Card> cards = new LinkedList<>(); for (Pattern p : Pattern.values()) { for (int i = 1; i <= 13; i++) { Card c = new Card(p, i); cards.add(c); } } return cards; } public Card pick() { int randomIndex = (int) (Math.random() * cards.size()); return cards.remove(randomIndex); } } ``` 여기서 values() 가 오류가 뜨는데 어떻게 해야될까요>?
