本文整理了Java中org.apache.commons.io.FilenameUtils.indexOfLastSeparator()方法的一些代码示例，展示了FilenameUtils.indexOfLastSeparator()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。FilenameUtils.indexOfLastSeparator()方法的具体详情如下：
包路径：org.apache.commons.io.FilenameUtils
类名称：FilenameUtils
方法名：indexOfLastSeparator
[英]Returns the index of the last directory separator character.
This method will handle a file in either Unix or Windows format. The position of the last forward or backslash is returned.
The output will be the same irrespective of the machine that the code is running on.
[中]返回最后一个目录分隔符字符的索引。
此方法将处理Unix或Windows格式的文件。返回最后一个向前或向后斜杠的位置。
无论代码在哪台机器上运行，输出都是相同的。
