我正在创建一个德州扑克游戏，如果您知道扑克，这很简单。
我正在研究SevenCardHand类，该类基本上在构造函数中使用7张卡的ArrayList。我正在创建用于查找7张牌的手的等级的算法（无论是同花，顺子，对子还是三张同等...）
但是有些手出现的几率很低，因此要测试这一点，我想自动处理整手牌。因此，我循环遍历创建新的SevenCardHands并打印它们是否齐平（我正在测试的是齐平的）]
问题是，它不会让我用for循环创建超过7手牌。该程序不会终止，但是不会取得任何进一步的进展。不管我做了什么，冻结之前它的产量都不会超过7。
这是我的Card，DeckOfCards，HoldEmDriver和SevenCardHand类中的代码

如果您要查找的是某人在七张牌中有同花的几率，我不完全确定为什么要使用double-for循环来执行此操作。据我所知，外部循环在这里给您带来麻烦，因为它只要求7张新的7张牌。要增加样本量，我可以尝试以下方法：
int count = 0;
int not_flush = 0;
int is_flush = 0;
while (count < 1000) {
cards.clear();
for(int i=0; i<7; i++) {
cards.add(theDeck.dealCard());
}
seven = new SevenCardHand(cards);
if (seven.hasFlush()) {
is_flush++;
}
else {
not_flush++;
}
count++;
}
float result = (float)is_flush/(float)not_flush;
