title: how to add months to the date without Calendar?
body: <p>I'm now developing gwt project that want to add month to the given date. gwt doesn't support Calendar class so how can I do this ? Date is in <code>"dd.MM.yyyy"</code> format</p>
  
  <pre><code>public Date addMonth(Date d, int months){
  }
  </code></pre>
  
  <p>mine implementation is so long that I need help. Thanks</p>
  
  <p><strong>[EDIT]</strong></p>
  
  <p>addMonth() means just add months to the given date's month. If it is <code>01.06.2010</code> adding 4 months is <code>01.10.2010</code></p>
  
  <p>for 31 Jan and add 1 it will 28. Feb</p>
