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

Character.getName介绍

[英]Returns a human-readable name for the given code point, or null if the code point is unassigned.

As a fallback mechanism this method returns strings consisting of the Unicode block name (with underscores replaced by spaces), a single space, and the uppercase hex value of the code point, using as few digits as necessary.

Examples:

  • Character.getName(0) returns "NULL".
  • Character.getName('e') returns "LATIN SMALL LETTER E".
  • Character.getName('\u0666') returns "ARABIC-INDIC DIGIT SIX".
  • Character.getName(0xe000) returns "PRIVATE USE AREA E000".

Note that the exact strings returned will vary from release to release.
[中]返回给定代码点的可读名称，如果未指定代码点，则返回null。
作为一种回退机制，此方法返回由Unicode块名（下划线替换为空格）、单个空格和代码点的大写十六进制值组成的字符串，并根据需要使用少量数字。
示例：
*性格。getName（0）返回“NULL”。
*性格。getName（'e'）返回“拉丁文小写字母e”。
*性格。getName（'\u0666'）返回“阿拉伯-印度数字六”。
*性格。getName（0xe000）返回“私有使用区域E000”。
请注意，返回的确切字符串因版本而异。
