我的情况是我在一个房间里有一套玩家，每个玩家手里都有一套牌。
HashMap<Integer,ArrayList<Integer>> useridToCardsinTheirHand = new HashMap<Integer, ArrayList<Integer>>();
任何玩家都可以“拨打电话”。 我需要检查进行“通话”的玩家是否具有最低价值 （总卡的最小值）。
要继续上述逻辑，我再次使用LinkedhashMap
private static LinkedhashMap<Integer,Integer> useridTotalRank = new LinkedhashMap<Integer,Integer>();
如果值中存在平局，则会执行优先级算法。
我在所有逻辑中使用hashMap。
因为我使用的是HashMaps，所以我遇到了问题。逻辑流程很笨拙。
我打算重新设计。我正在通过MultiMap，但仍然预见到类似的问题。 我可以就所使用的馆藏类型提出建议。
我尝试过的伪代码是::

答案 0 :(得分：1)
请为Room，Player和Card提供简单的Java bean（可能不需要Card）等。这样，您可以在将来有新要求时更改类的属性。最终你只需要管理List Room，这样如果你得到一个Room对象，你可以轻松地从它中检索玩家等等。
Class Room{
String roomName;
String location;
String List<Player>;
// have getters setters for each of them
}
这样它也更易于管理，因此处理代码（如果有的话）只能将它们放在相关的类中。例如在房间类中，您可以使用一个名为getLeastValueCard的方法，该方法为该用户返回该用户，您可以为整个房间进行循环。
希望这是有道理的。
