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

Character.highSurrogate介绍

[英]Returns the high surrogate for the given code point. The result is meaningless if the given code point is not a supplementary character.
[中]返回给定代码点的高代理项。如果给定的代码点不是补充字符，则结果没有意义。
