本文整理了Java中java.lang.Character.codePointAt()方法的一些代码示例，展示了Character.codePointAt()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.codePointAt()方法的具体详情如下：
包路径：java.lang.Character
类名称：Character
方法名：codePointAt
[英]Returns the code point at index in the specified sequence of character units. If the unit at index is a high-surrogate unit, index + 1 is less than the length of the sequence and the unit at index + 1 is a low-surrogate unit, then the supplementary code point represented by the pair is returned; otherwise the charvalue at index is returned.
