如何使路径名与不同的操作系统兼容？

Question

I used to know it, but I know there is a way in java to make sure the path works in all OSs (Windows uses a different "/" system than Unix based systems). What do I have to do to create a file path name that works with all systems?

EDIT: I wasn't sure if this is what I meant, but I think the file path will end up being relative.

Also, what's the difference between File.separator and File.pathSeparator ?

Answer 1

You'll have to use File.separator or File.separatorChar for this purpose.
Check the File class javadoc for more info on this.

edit: Difference between separator and pathSeparator . The first separates the folder in a file's path like the / in /usr/bin . The second one is a separator in a path environment variable, like the ; in PATH=C:/windows/bin;C:/anotherfolder

Answer 2

You can just use / (forward slash) as the path separator. That will work cross-platform.

Answer 3

File带有分隔符

Answer 4

除了不确定它的受欢迎程度外，我以前已经使用过它。

System.getProperty("file.separator");
