title: java iterate over map except last iteration
body: <p>I have the next map <strong>values</strong>:</p>
  
  <pre><code>{title=varchar(50), text=text}
  </code></pre>
  
  <p>I am trying to convert it into two strings like this:</p>
  
  <pre><code>StringBuffer string = new StringBuffer();
  for (String keyinside: values.keySet()) {
      string.append(keyinside + " " + values.get(keyinside) + ", ");
  }
  </code></pre>
  
  <p>But what I want here - not inlude ", " at the last iteration. How can I do it?</p>
