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

FileUtils.forceDelete介绍

[英]Deletes a file. If file is a directory, delete it and all sub-directories.

The difference between File.delete() and this method are:

  • A directory to be deleted does not have to be empty.
  • You get exceptions when a file or directory cannot be deleted. (java.io.File methods returns a boolean)
    [中]删除一个文件。如果文件是一个目录，请删除它和所有子目录。
    文件之间的差异。delete（）和此方法是：
    *要删除的目录不必为空。
    *无法删除文件或目录时会出现异常。（java.io.File方法返回布尔值）
