l am a little puzzled, why the file's behavior like this:

                File fl = new File("","1.txt");
        System.out.println(fl.getName());
        System.out.println(fl.getParent());
        System.out.println(fl.getPath());
        System.out.println(fl.getAbsolutePath());
        try {
            System.out.println(fl.getCanonicalPath());
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

the output is:
1.txt
\
\1.txt
D:\1.txt
D:\1.txt

why "" path, java process it as "/"?

From the docs

"If parent is the empty abstract pathname then the new File instance is
created by converting child into an abstract pathname and resolving the
result against a system-dependent default directory."
