title: DirectoryStream return path in what kind of order? filename, last modified, filesize?
body: <p>I am trying to read multiple files in a folder using DirectoryStream. There are 10 items altogether. </p>
  
  <blockquote>
    <p>doc_01.txt, doc_02.txt, doc_03.txt, doc_04.txt, doc_05.txt, doc_06.txt, doc_07.txt, doc_08.txt, doc_09.txt, doc_10.txt</p>
  </blockquote>
  
  <p>I wanted the file to be read in the order of their filename.
  Does DirectoryStream read the file in order of their filename? Because this is the result I get:</p>
  
  <blockquote>
    <p>./mydata/doc_01.txt, ./mydata/doc_02.txt, ./mydata/doc_03.txt, ./mydata/doc_04.txt, ./mydata/doc_08.txt, ./mydata/doc_07.txt, ./mydata/doc_09.txt, ./mydata/doc_10.txt, ./mydata/doc_05.txt, ./mydata/doc_06.txt</p>
  </blockquote>
  
  <p>This is my code:</p>
  
  <pre><code>public static void readData(){
      Instant start = Instant.now();
      System.out.println("Start reading");
  
      Path path = Paths.get(String.join(File.separator, ".", "mydata"));
  
      try(DirectoryStream&lt;Path&gt; stream = 
              Files.newDirectoryStream(path, "*.txt")
      ){
          for(Path entry : stream){
              System.out.println("reading: " +entry.toString());
          }
      }catch(IOException e){
          System.err.println("Error: " + e.getMessage());
          e.printStackTrace();
      }
      Instant end = Instant.now();
      System.out.println("Done in " + Duration.between(start, end).toString());
  }
  </code></pre>
