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

File.getAbsolutePath介绍

[英]Returns the absolute path of this file. An absolute path is a path that starts at a root of the file system. On Android, there is only one root: /.

A common use for absolute paths is when passing paths to a Process as command-line arguments, to remove the requirement implied by relative paths, that the child must have the same working directory as its parent.
[中]返回此文件的绝对路径。绝对路径是从文件系统的根开始的路径。在Android上，只有一个根：/。
绝对路径的一个常见用法是将路径作为命令行参数传递给进程，以消除相对路径所隐含的要求，即子进程必须具有与其父进程相同的工作目录。
