java - 打印不同的数组元素

Question

我想像这样显示不同的字符串数组元素:

• 俱乐部 1
• 红心王牌
• 钻石 9

卡片游戏.java:

public class CardGame {
    public static void main(String[] args){
        String[] suit = { "Clubs", "Hearts", "Diamonds", "Spades" };
        String[] deck = { "2", "3", "4", "5", "6", "7", "8", "9", "10",
                        "Jack", "Queen", "King", "Aces" };

        int i = (int) ( Math.random() * deck.length );
        int j = (int) ( Math.random() * suit.length );


        for( int a = 0; a < 7; a++ ) {
            System.out.println( "Deck " + deck[i] + " Suit " + suit[j] );
        }

        System.out.println();
    }
}

我该怎么做？指出我正确显示这些不同元素的逻辑。谢谢。

放

int i = (int) ( Math.random() * deck.length );
int j = (int) ( Math.random() * suit.length );

进入for循环，这样每次迭代都会生成一张新的随机卡片
