title: create a text file in a folder
body: <p>I want to create a text file into that folder that I am creating here. </p>
  
  <pre><code>File dir = new File("crawl_html");  
  dir.mkdir(); 
  String hash = MD5Util.md5Hex(url1.toString());
  System.out.println("hash:-"  + hash);
  File file = new File(""+dir+"\""+hash+".txt");
  </code></pre>
  
  <p>But this code doesn't create the text file into that folder..Instead it makes the text file outside that folder..</p>
