使用IEqualityComparer（TKey）的C＃Dictionary的Java模拟

[英]Java analogue of C# Dictionary with IEqualityComparer(TKey)

原文 2012-03-01 10:25:12 7 1 c#/ java/ dictionary/ map/ comparator

Is there a Map-based class in Java (in lang, apache commons or somewhere else) which has possibility to provide custom key equality comparer? Java中是否存在基于Map的类（在lang，apache commons或其他地方），它有可能提供自定义键相等比较器吗？

In C# it is possible with Dictionary class http://msdn.microsoft.com/en-us/library/ms132072.aspx . 在C＃中，可以使用Dictionary类http://msdn.microsoft.com/en-us/library/ms132072.aspx 。

是的，您可以使用自定义比较器构建 TreeMap
