因此，首先我有一副牌，其中数字2-14作为俱乐部或[0]-[12]在Card[]对象中，价值（等级）2-14为钻石[13]-[25]，红心[26]-[38]，黑桃[39]-[51]。

然后，我必须通过在shaffle（）类（例如…

//Holds an array of card objects
private Card [] cards  = new Card [52];

//Holds number of cards remaining in deck
private int count;

public Deck()
{
    for (int i = 0; i <= 12; i++) {
        cards[i] = new Card(i+2, 'C');
        count = 52-13;
    }

    for (int i = 13; i <= 25; i++) {
        cards[i] = new Card(i-13+2, 'D');
        count = 39-13;
    }

    for (int i = 26; i <= 38; i++) {
        cards[i] = new Card(i-26+2, 'H');
        count = 26-13;
    }

    for (int i = 39; i <= 51; i++) {
        cards[i] = new Card(i-39+2, 'S');
        count = 13-13;
    }
}

public void shuffle()
    {
        for (int i = 0; i <= 51; i++)
            if (i <= 12) 
                cards[i] = new Card((int)(Math.random() * 52), 'C');
            else if (i <= 25) 
                cards[i] = new Card((int)(Math.random() * 52), 'D');
            else if (i <= 38) 
                cards[i] = new Card((int)(Math.random() * 52), 'H');
            else if (i <= 51) 
                cards[i] = new Card((int)(Math.random() * 52), 'S');


    }

这将数字2-14的值更改为从0-51的随机整数，我唯一不明白的部分是如何取那个随机整数来替换我的值2-14，并使其（例如）卡[14]=35，然后用卡[35]交换卡[14]。我没有使用集合或数组列表的经验。
