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

This is what Apache commons-io does, unrolled into a couple of lines of code:

String separatorsToSystem(String res) {
    if (res==null) return null;
    if (File.separatorChar=='\\') {
        // From Windows to Linux/Mac
        return res.replace('/', File.separatorChar);
    } else {
        // From Linux/Mac to Windows
        return res.replace('\\', File.separatorChar);
    }
}

So if you want to avoid the extra dependency, just use that.
