  <pre><code>SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
  if(petDetails.getDateOfDeath() != null){
      String  formatedDateOfDeath = formatter.format(petDetails.getDateOfDeath());
      String formateDateOfBirth = formatter.format(petDetails.getDateOfBirth());
  }
  </code></pre>

  <p><strong>EDIT:</strong> please look at what I've got so far.none of the other threads are like mine. most of them are about date from DOB to today and not in the format im using.</p>
