Java错误 <identifier> 预期

Question

I am currently working on a Poker java game exercise, and I get this ugly error which I'm not being able to understand. It must be some kind of syntax error since the compiler throws 100 of those. But I just don't know where the error is??

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;
            ...

though I am not able to spot any syntax error?

Btw, the Card is a separate class.

Answer 1

There's no reason why the variable triples can't be assigned where you are indicating the error.

However, you need to assign the String arrays like so:

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

Your syntax for initializing the array values is incorrect.

I'm not sure why the compiler is waiting an additional four lines before it starts complaining, but your array declaration is invalid several lines above.

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

Should be like this...

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

You can only use the first structure if you are initializing it on the same line you declare it, like this:

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

Answer 3

I realise that an answer has already been accepted here but I wanted to point out that it's easier to initialise your variables at their point of declaration if they don't rely on any parameters of the constructor, ie

public class Poker
{
    private static final int NUMBER_OF_CARDS = 52;
    private Card[] deck = new Card[ NUMBER_OF_CARDS ];
    private int numbers[] = new int[ 13 ]
    private int triples = 0;
    private int couples = 0;
    private String faces[] = { "Ace", "Deuce", "Three", "Four", "Five", "Six", "Seven",
                               "Eight", "Nine", "Ten", "Jack", "Queen", "King"};
    private String suits[] = { "Hearts", "Diamonds", "Clubs", "Spades" };

etc.
