有序地图实施

Question

我正在寻找一个Map实现,它按照添加顺序迭代键值对.例如

Map orderedMap = // instantiation omitted for obvious reasons :)
orderMap.put(4, "d");
orderMap.put(10, "y");
orderMap.put(2, "b");

for (Map.Entry entry : orderedMap.entrySet()) {
  System.out.println(entry.getKey() + ", " + entry.getValue());
}

将永远打印

4, d
10, y
2, b

我正在使用Java 5.0.

谢谢,唐
