title: Java convert string in iso_instant format to date
body: <pre><code>String timeString = "2016-02-18T20:15:37.421Z";
  </code></pre>
  
  <p>How do I convert this into Date object? I tried something like this</p>
  
  <pre><code>DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
  String timeString = "2016-02-18T20:15:37.421Z";
  Date date= dateFormat.parse(timeString);
  </code></pre>
  
  <p>That gives me an Unparseable date exception</p>
