本文整理了Java中java.lang.Character.lowSurrogate()
方法的一些代码示例,展示了Character.lowSurrogate()
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.lowSurrogate()
方法的具体详情如下:
包路径:java.lang.Character
类名称:Character
方法名:lowSurrogate
[英]Returns the low surrogate for the given code point. The result is meaningless if the given code point is not a supplementary character.
[中]返回给定代码点的低代理项。如果给定的代码点不是补充字符,则结果没有意义。
