本文整理了Java中org.apache.commons.io.FileUtils.listFilesAndDirs()方法的一些代码示例，展示了FileUtils.listFilesAndDirs()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。FileUtils.listFilesAndDirs()方法的具体详情如下：
包路径：org.apache.commons.io.FileUtils
类名称：FileUtils
方法名：listFilesAndDirs

FileUtils.listFilesAndDirs介绍

[英]Finds files within a given directory (and optionally its subdirectories). All files found are filtered by an IOFileFilter.

The resulting collection includes the subdirectories themselves.
[中]查找给定目录（及其子目录）中的文件。找到的所有文件都由IOFileFilter筛选。
生成的集合包括子目录本身。
