title: Sum two dates in Java
body: <p>How can I add two dates in Java?</p>
  
  <p>Example: The sum of  "2010-01-14 19:16:17" "0000-10-03 01:10:05"<br>
  would result in "2010-11-17 20:26:22".</p>
  
  <p>I know how to do it using Calendar and adding field by field.</p>
  
  <p>Is any other way to sum them all (year/month/day/hour/minute/second) at once?</p>
