How to get the relative path name?

Question

I am wondering how to get the relative path name? Any existing library can help this?

c:\123 c:\123\1234\zaq\erf

I would like to get something like 123/1234/zaq/erf

you are saying that `c:\123 c:\123\1234\zaq\erf` will be passes as an argument and output is `123/1234/zaq/erf`? — havexz, Dec 12 '11 at 02:42

Use the relativize() method in the URI class. Construct a URI from the base file path and then relativize your absolute file path.

String s = new File("c:\\123").toURI().relativize(new File("c:\\123\\1234\\zaq\\erf").toURI()).getPath();

If you are using Java 7, there is the relativize method of the Path class that does what you need.
