本文整理了Java中java.util.Dictionary类的一些代码示例，展示了Dictionary类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Dictionary类的具体详情如下：
包路径：java.util.Dictionary
类名称：Dictionary

Dictionary介绍

[英]Note: Do not use this class since it is obsolete. Please use the Map interface for new implementations.

Dictionary is an abstract class which is the superclass of all classes that associate keys with values, such as Hashtable.
[中]注意：不要使用此类，因为它已过时。请使用映射接口进行新的实现。
Dictionary是一个抽象类，它是所有将键与值关联的类（如Hashtable）的超类。
