}恩，有一些漏洞，应该用collection.shuffle（），方法，不过我当时不知道这个方法，谢谢各位了，多多学习
然后 game方法 中对比的应该是2个较大的手牌么？，
if (compare.compare(player.get(0).handPoker.get(0),
player.get(1).handPoker.get(1)) > 0)
此句第一个handPoker.get(0),应该是较小那一个，是否该改为handPoker(1) ?
洗牌部分真的洗牌了吗？
这样多次运行结果应该不会变，因为并没有洗牌，只是把newpoker赋值了poker，然而前面应该加一句 Collections.shuffle(poker);
才可做到洗牌效果吧？
可能不对，考虑考虑
Controller 中 创建Poker 语句
for (Poker pk : poker) {
System.out.print(pk + ",");
}
为什么我输出的是地址符？
代码无懈可击，但我觉得有个地方可能有问题：
老师要求随机洗牌后按顺序从第一张扑克开始发牌，用Set（无序的）集合，用迭代器取牌并不符合发牌规则，这更像从扑克牌中随机取牌，如果洗牌后的排序不变，你的发牌出现的结果是随机的：
// 发牌
public void deal() {
System.out.println("----------开始发牌----------");
for (int i = 0; i < 2; i++) {
for (int j = 0; j < 2; j++) {
Iterator<Poker> it = newPoker.iterator();
Poker poker = it.next();
player.get(j).handPoker.add(poker);
System.out.println("玩家" + player.get(j).getName() + "拿牌");
newPoker.remove(poker);
}
}
System.out.println("----------发牌结束----------");
}Set<Poker> newPoker; //代码中洗牌后的扑克牌的集合
