本文整理了Java中java.util.Hashtable.put()方法的一些代码示例，展示了Hashtable.put()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。Hashtable.put()方法的具体详情如下：
包路径：java.util.Hashtable
类名称：Hashtable
方法名：put

Hashtable.put介绍

[英]Associate the specified value with the specified key in this Hashtable. If the key already exists, the old value is replaced. The key and value cannot be null.
[中]将指定值与此哈希表中的指定键相关联。如果密钥已存在，则替换旧值。键和值不能为null。
