用Java替换过时的Hashtable类 [英] Replacement for obsolete Hashtable class in Java

问题描述

当我尝试使用散列表类时，Netbeans给了我一个错误说：

When I tried to use the hashtable class, Netbeans gave me an error saying:

虽然仍然支持，但这些类已经过时了由JDK1.2集合类，并且可能不应该在新开发中使用。

While still supported, these classes were made obsolete by the JDK1.2 collection classes, and should probably not be used in new development.

然而，我似乎无法找到更好地替换 Hashtable 的在线示例。有什么建议吗？

However, I can't seem to find an example online on a better replacement for Hashtable. Any suggestions?

推荐答案

Hashtable 是 HashMap 。

可能重要的一个区别是 Hashtable 的所有相关方法都是同步的它们在 HashMap 上不同步。

One difference that could be important is that all relevant methods of Hashtable are synchronized while they are not synchronized on HashMap.
