title: How do I enumerate the keys and values of a Hashtable?
body: <p>I have a problem ; I have some data and I show it with <code>Hashtable</code> 
  for example I write :</p>
  
  <pre><code> Enumeration keys;
      keys=CellTraffic_v.elements();
      while(keys.hasMoreElements())
        outputBuffer.append(keys.nextElement()+"\n\n");
  </code></pre>
  
  <p>but it show me just values how can i show values and keys together?
  for example this</p>
  
  <p>if my key be "A"
  and my value be "B" show me this :</p>
  
  <pre><code>A  B
  </code></pre>
  
  <p>Thanks ...</p>
