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

Charset.aliases介绍

[英]Returns an unmodifiable set of this charset's aliases.
[中]返回此字符集别名的不可修改集。

代码示例

/**
 * Returns whether a given encoding is UTF-8. If the given name is null, then check the platform's default encoding.
 *
 * @param charsetName If the given name is null, then check the platform's default encoding.
 */
static boolean isUTF8(String charsetName) {
  if (charsetName == null) {
    // check platform's default encoding
    charsetName = Charset.defaultCharset().name();
  }
  if (StandardCharsets.UTF_8.name().equalsIgnoreCase(charsetName)) {
    return true;
  }
  for (final String alias : StandardCharsets.UTF_8.aliases()) {
    if (alias.equalsIgnoreCase(charsetName)) {
      return true;
    }
  }
  return false;
