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

Charset.availableCharsets介绍

[英]Returns an immutable case-insensitive map from canonical names to Charset instances. If multiple charsets have the same canonical name, it is unspecified which is returned in the map. This method may be slow. If you know which charset you're looking for, use #forName.
[中]返回从规范名称到字符集实例的不可变的不区分大小写的映射。如果多个字符集具有相同的规范名称，则在映射中返回未指定的名称。这种方法可能很慢。如果您知道要查找哪个字符集，请使用#forName。
