• We have seen in previous example if we use Paths.get(.) to print absolute path of current directory its prints a /. at the end of the path of our current directory.
• In the below example we use . to get the absolute path of current project then use files to go to files path then use .. to go on level up then again go to files and then go to SubDirectoryFile.txt
• Please note its better to use normalise when printing contents of a file when we are building path based on dots(..)
• Then we use helper method printFile to print contents of the file.

   subDirPath  = FileSystems.getDefault().getPath(".","files","..","files","SubDirectoryFile.txt");
   System.out.println("The normalised path is ----->"+subDirPath.normalize().toAbsolutePath());
   printFile(subDirPath.normalize());

Helper method to print contents of file

  public static void printFile(Path path){
        try(BufferedReader fileReader = Files.newBufferedReader(path)){
            String line;
            while((line=fileReader.readLine())!=null){
                System.out.println(line);
            }

        } catch (IOException e) {
            System.out.println(e.getMessage());
            e.printStackTrace();
        }
}
