這可能是一個(gè)有點(diǎn)太基本的問題。我已經(jīng)嘗試了已經(jīng)給出的方法，但它不起作用。我想從另一個(gè)班級調(diào)用 ENUM。   package com.blackjack.game.cards;public enum Card implements Comparable<Card> {    ACE(1, 11),    KING(13, 10),    QUEEN(12, 10),    JACK(11, 10),    TEN(10, 10),    NINE(9, 9),    EIGHT(8, 8),    SEVEN(7, 7),    SIX(6, 6),    FIVE(5, 5),    FOUR(4, 4),    THREE(3, 3),    TWO(2, 2);    public final int rank;    public final int value;    private static final String[] CARD_NAMES = {            "joker", "ace", "two", "three",            "four", "five", "six", "seven",            "eight", "nine", "ten", "jack",            "queen", "king"    };    private Card(final int rank, final int value) {        this.rank = rank;        this.value = value;    }    public int getRank() {        return rank;    }    public int getValue() {        return value;    }我正在按以下方式進(jìn)行操作，但它不起作用。import com.blackjack.game.cards.Card;Card card = new Card.ACE;
