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

FileUtils.contentEquals介绍

[英]Compares the contents of two files to determine if they are equal or not.

This method checks to see if the two files are different lengths or if they point to the same file, before resorting to byte-by-byte comparison of the contents.

Code origin: Avalon
[中]比较两个文件的内容以确定它们是否相等。
在对内容进行逐字节比较之前，此方法检查两个文件的长度是否不同，或者它们是否指向同一个文件。
