java - 在Java中将索引附加到多维数组

public class NewDeck {

    public static void main(String[] args){

        String[] suits = new String[] {"Clubs", "Diamonds", "Spades", "Hearts"};

        String[] faces = new String[] {"Ace", "King", "Queen", "Jack"};

        String[][] deck = new String[][] {{},{}};

        int a = 0;
        int b = 0;

        for(String x: suits){

            a ++;

            for(String y: faces){


                deck[a][b] = {{x, y}};  // THIS IS THE LINE I NEED HELP WITH

                b++;

        System.out.println(deck);

            }

        }

    }

}

我希望打印的是：

{{"Clubs, "Ace"}{"Diamonds", "Ace"}{"Spades", "Ace"}{"Hearts", "Ace"}
 {"Clubs, "King"}{"Diamonds", "King"}{"Spades", "King"}{"Hearts", "King"}
 {"Clubs, "Queen"}{"Diamonds", "Queen"}{"Spades", "Queen"}{"Hearts", "Queen"}
 {"Clubs, "Jack"}{"Diamonds", "Jack"}{"Spades", "Jack"}{"Hearts", "Jack"}

当我要打印时：

deck[4][0]

我希望它能打印：

"Clubs"

我知道我非常接近，只有一条线我认为我做错了，所以我评论了引起问题的那条线。如果有人知道要放什么，而不是：

deck[a][b] = {{x, y}};

将不胜感激。

最佳答案

public static void main(String args[]) {
    String suits[] = new String[] {"Clubs", "Diamonds", "Spades", "Hearts"};
    String faces[] = new String[] {"Ace", "King", "Queen", "Jack"};
    String deck[][] = new String[suits.length * faces.length][2];

    int i=0;

    for (String suit : suits) {
        for (String face : faces) {
            deck[i][0] = suit;
            deck[i][1] = face;
            i++;
        }
    }
}
