title: How to convert / cast long to String?
body: <p>I just created sample BB app, which can allow to choose the date.</p>
  
  <pre><code>DateField curDateFld = new DateField("Choose Date: ",
    System.currentTimeMillis(), DateField.DATE | DateField.FIELD_LEFT);
  </code></pre>
  
  <p>After choosing the date, I need to convert that long value to String, so that I can easily store the date value somewhere in database.
  I am new to Java and Blackberry development.</p>
  
  <pre><code>long date = curDateFld.getDate();
  </code></pre>
  
  <p>How should I convert this long value to String? Also I want to convert back to long from String. I think for that I can use <code>long l = Long.parseLong("myStr");</code>?</p>
