Question

我目前正在进行一场扑克java游戏练习，我得到了一个我无法理解的丑陋错误。它必须是某种语法错误，因为编译器会抛出其中的100个。但我只是不知道错误在哪里？

import java.util.Random;

public class Poker
{
    private Card[] deck;
    private Card[] hand;
    private int currentCard;
    private int numbers[], triples, couples;
    private String faces[], suits[];

    private boolean flushOnHand, fourOfAKind, isStraight;
    private static final int NUMBER_OF_CARDS = 52;

    private static final Random randomNumbers = new Random();

    Poker()
    {
        faces = { "Ace", "Deuce", "Three", "Four", "Five",
            "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};
        suits = { "Hearts", "Diamonds", "Clubs", "Spades" };

        numbers = new int[ 13 ];

        deck = new Card[ NUMBER_OF_CARDS ];

        triples = 0; // right here's where the compiler starts complaining
        couples = 0;
            ...

虽然我无法发现任何语法错误？

顺便说一句，Card是一个单独的类。

Answer 1

没有理由在指示错误的地方无法分配变量triples。

但是，您需要像这样分配String数组：

faces = new String[] { "Ace", "Deuce", "Three", "Four", "Five",
         "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};
suits = new String[] { "Hearts", "Diamonds", "Clubs", "Spades" };

Answer 2

初始化数组值的语法不正确。

我不确定为什么编译器在开始抱怨之前还要等待额外的四行，但是你的数组声明在上面几行无效。

    faces = { "Ace", "Deuce", "Three", "Four", "Five",
        "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};
    suits = { "Hearts", "Diamonds", "Clubs", "Spades" };

应该是这样......

    faces = new String[] { "Ace", "Deuce", "Three", "Four", "Five",
        "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};
    suits = new String[] { "Hearts", "Diamonds", "Clubs", "Spades" };

如果您在声明它的同一行初始化它，则只能使用第一个结构，如下所示：

private String faces[] = { "Ace", "Deuce", "Three", "Four", "Five",
        "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};
private String suits[] = { "Hearts", "Diamonds", "Clubs", "Spades" };
