Assumed I have an existed list, how can I add an element to it at run time? I do as follow:

...
   List newList = new ArrayList();
   List oldList = myObject.getList();
   MyElement newEle = new MyElement();
   for(int i=0; i<oldList.size(); i++)
      newList.add(oldList.get(i));
   newList.add(neEle);
...

I think this way seems not so elegent. Someone has any better idea?
