Java 获取文件的创建时间

     File file = new File("D:\\22222.txt");
       SimpleDateFormat dateFormat = new SimpleDateFormat("YYYY-MM-dd");
       FileTime t = null;
    try {
      t = Files.readAttributes(Paths.get("D:\\22222.txt"), BasicFileAttributes.class).creationTime();
    } catch (IOException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
       System.out.println(dateFormat.format(t.toMillis()));
