title: Does Hashmap autosort?
body: <p>This is my hashmap :</p>
  
  <pre><code>HashMap&lt;Long, Day&gt; hashMapTest = new HashMap&lt;Long, Day&gt;();
  </code></pre>
  
  <p>and I insert <code>Date.getTime()</code> into this hashmap like :</p>
  
  <pre><code>Date start = new Date(vonDatum.getTime());
  
  for (int i = 0; i &lt; tagediff; i++)
    {
      Day day= new Day(start);
      this.mitarbeiterTagHashMap.put(start.getTime(), day);
      CalendarUtil.addDaysToDate(start, 1);
    }
  </code></pre>
  
  <p>The strange thing is when I call the hashmap with, the order is completely an other and the keys doesnt fit to the insertion :</p>
  
  <pre><code>for (Long name : hashMapTest.keySet())
   {
       Window.alert(name + ": " + hashMapTest.get(name));
   }
  </code></pre>
