About Question enthuware.ocpjp.v7.2.1602 :

[Chen@ukr.net]

an empty path is returned if this path does have a root component and all name elements are redundant

but i try:

Code: Select all

Path p = Paths.get("C:\\\\..");
        System.out.println(p.normalize());
        //C:\

i can`t repeat condition:

an empty path is returned if this path does have a root component and all name elements are redundant

my assumption that must be
an empty path is returned if this path does not have a root component and all name elements are redundant

By the way, I tried this code on Linux (Ubuntu) and found that

Code: Select all

normalize()

doesn't work for Windows path
On my machine it work only for paths like /home/foo/bar/../..
