How come

Paths.get("\\index.html");

has root. The root under linux is / and for windows is c:\

It considers a path starting with \\ as root as well. Although they haven't specified an exact definition of a root anywhere.

You may want to try it out.

I'm don't understand why Explanation is saying that "if a path starts with a // or c:" has a root, but example is with "\\"
Paths.get("\\index.html");

It doesn't matter if it's starting with "\\" or "//", that's always a root?

Thanks

Well, On *nix systems, path separator is /, a path starting with \ is not root.

Prints the following on my linux box:
../\index.html

To run the code in linux, you need to create the path object like this because the root in Linux is "/"...

I want to know in the real exam, do they specified which OS they using? If not , it seems like ambiguous about the separator...

In the exam, you can assume that if the separater is /, then the code is for linux and if it is \\, then the code is for windows.

HTH,
Paul.

So on nix systems I am assuming "/" has to escaped to "//" hence the code in question also causes error? Am I right?

No, on a *nix based system, you do not need to escape /.
