一、Hashtable是原始的java.util的一部分, 是一个Dictionary具体的实现 。 然而,Java 2 重构的Hashtable实现了Map接口,因此,Hashtable现在集成到了集合框架中。它和HashMap类很相似,但是它支持同步。像HashMap一样,Hashtable在哈希表中存储键/值对。当使用一个哈希表,要指定用作键的对象,以及要链接到该键的值。
Java - The Hashtable Class - Hashtable was part of the original java.util and is a concrete implementation of a Dictionary.
(The HashMap class is roughly equivalent to Hashtable, except that it is unsynchronized and permits nulls.) This class makes no guarantees as to the order of the map; in particular, it does not guarantee that the order will remain constant over time. This implementation provides constant-...
