java中文件路径的Windows转义序列问题 [英] Windows escape sequence issue with file path in java

问题描述

我需要使用 windows 文件路径对文件进行一些操作，但我收到了无效的转义序列错误.

I need to use windows file path to do some operation on files but i am getting invalid escape sequence error.

File f = new File("C:	est");

系统只接受\"或/"，但如果我从windows复制文件路径，它是".我该如何解决这个问题

the system accepts only " \ " or "/" but if I copy file path from windows it is with "". how can i solve this issue

推荐答案

使用 File.seperator 代替".

Use File.seperator in place of "".

File f = new File("C:"+File.seperator+"test");

File.seperator 返回"并且它不被视为转义字符.

File.seperator returns "" and it is not treated as an escape character.

如果您的文件 test.txt 保存在文件夹 D:/MyFloder/MyPrograms 中，您可以执行以下操作

If your file test.txt is saved in folder D:/MyFloder/MyPrograms you can do something like this

File f = new File("D:"+File.seperator+"MyFloder"+File.seperator+"MyPrograms"+File.seperator+"test.txt");

编辑

您无需担心操作系统

对于 Unix:File.separator =/

对于 Windows:File.separator =

For Windows : File.separator =
