实现一个JAVA Card类，花色大小按黑桃，红心，方块，梅花排，先比较数字，数字相同情况下比较花色

随机输入五张扑克牌，比较其大小

int[] deck = new int[52];
String[] suits = { "黑桃","红心","方块"，"梅花" };
String[] ranks = { "A", "2", "3", "4", "5", "6", "7", "8", "9", "10",
"J", "Q", "K" };
for (int i = 0; i < deck.length; i++)
deck[i] = i;
for (int i = 0; i < deck.length; i++) {
int index = (int) (Math.random() * deck.length);
int demp = deck[i];
deck[i] = deck[index];
deck[index] = demp;
}
for (int i = 0; i < 52; i++) {
for (int j = 0; j < 52 - i; j++)
if (deck[j] % 13 > deck[j + 1] % 13) {
int demp = deck[j];
deck[j] = deck[j + 1];
deck[j + 1] = demp;
}
}
for (int i = 0; i < 52; i++) {
for (int j = 0; j < 52 - i; j++)
if (deck[j] / 13 < deck[j + 1] /13
&& deck[j] % 13 == deck[j + 1] % 13) {
int demp = deck[j];
deck[j] = deck[j + 1];
deck[j + 1] = demp;
}
}

双重冒泡排序 for (int i = 0; i < size; i++) { for (int j = i + 1; j < size; j++) { Card cari = cards[i]; Card carj = cards[j]; if (cari.compareNum(carj)> 0) {// 比较点数 swap(cari, carj); } else if (cari.compareNum(carj)= 0 ) { if (cari.compareColor(carj)> 0) { // 再比较花色 swap(cari, carj); } } } }
