Is there a Java utility which will convert a String path to use the correct File separator char?

Question

I have developed a number of classes which manipulate files in Java. I am working on a Linux box, and have been blissfully typing new File(\"path/to/some/file\");

Answer 1

A "/path/to/some/file" actually works under Windows Vista and XP.

new java.io.File("/path/to/some/file").getAbsoluteFile()

> C:\path\to\some\file

But it is still not portable as Windows has multiple roots. So the root directory has to be selected in some way. There should be no problem with relative paths.

Edit:

Apache commons io does not help with envs other than unix & windows. Apache io source code:

public static String separatorsToSystem(String path) { 
    if (path == null) {
     return null;
    }
    if (isSystemWindows()) {
      return separatorsToWindows(path);
    } else {
      return separatorsToUnix(path);
    }
}
