Java：如何获取字符的Unicode名称（或其类型类别）？ [英] Java: How to get Unicode name of a character (or its type category)?

问题描述

Character 中的类定义了检查给定的 char 参数是否与某些Unicode字符相等或属于一些类型类别。

The Character class in Java defines methods which check a given char argument for equality with certain Unicode chars or for belonging to some type category. These chars and type categories are named.

如给定的javadoc中所述，命名字符的示例为

HORIZONTAL TABULATION ， FORM FEED ，...;

命名类型类别的示例为

SPACE_SEPARATOR ， PARAGRAPH_SEPARATOR ，...

As stated in given javadoc, examples for named chars are
HORIZONTAL TABULATION, FORM FEED, ...;
example for named type categories are
SPACE_SEPARATOR, PARAGRAPH_SEPARATOR, ...

c $ c> byte 或 int 而不是枚举，这些类型的名称在运行时被隐藏。

However, being byte or int values instead of enums, the name of these types are "hidden" at runtime.

因此，是否有可能在运行时获取字符和/或类型类型的名称？

推荐答案

JDK7将有一个

String getName(int codepoint)

函数（阅读：类java.lang.Character中的静态方法）将代码点转换为其官方Unicode

function (READ: a "static method" in class java.lang.Character) that will turn a codepoint into its official Unicode name.

Javadoc： http://docs.oracle.com/javase/7/docs/api/java/lang/Character.html#getName%28int%29
