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

Charset.displayName介绍

[英]Returns the name of this charset for the default locale.

The default implementation returns the canonical name of this charset. Subclasses may return a localized display name.
[中]返回默认区域设置的此字符集的名称。
默认实现返回此字符集的规范名称。子类可以返回本地化的显示名称。
