      if (dir.isDirectory()) {
         String[] children = dir.list();
         for (int i = 0; i < children.length; i++) {
            boolean success = deleteDir (new File(dir, children[i]));
            if (!success) {
               return false;
            }
         }
      }
      return dir.delete();
      System.out.println("The directory is deleted.");
   }
}
