类名称：StringUtils
方法名：swapCase

StringUtils.swapCase介绍

[英]Swaps the case of a String changing upper and title case to lower case, and lower case to upper case.

• Upper case character converts to Lower case
• Title case character converts to Lower case
• Lower case character converts to Upper case

For a word based algorithm, see org.apache.commons.lang3.text.WordUtils#swapCase(String). A null input String returns null.

StringUtils.swapCase(null)                 = null 
StringUtils.swapCase("")                   = "" 
StringUtils.swapCase("The dog has a BONE") = "tHE DOG HAS A bone"

NOTE: This method changed in Lang version 2.0. It no longer performs a word based algorithm. If you only use ASCII, you will notice no change. That functionality is available in org.apache.commons.lang3.text.WordUtils.
[中]将字符串的大小写交换为大写，将标题大小写替换为小写，将小写替换为大写。
*大写字符转换为小写
*标题大小写字符转换为小写
*小写字符转换为大写
有关基于单词的算法，请参见org。阿帕奇。平民lang3。文本WordUtils#swapCase（字符串）。空输入字符串返回空值。

StringUtils.swapCase(null)                 = null 
StringUtils.swapCase("")                   = "" 
StringUtils.swapCase("The dog has a BONE") = "tHE DOG HAS A bone"

注意：此方法在Lang版本2.0中更改。它不再执行基于单词的算法。如果只使用ASCII，则不会注意到任何更改。该功能在org中可用。阿帕奇。平民lang3。文本WordUtils。
