How to replace an element in an existed list?

Assumed a list has 3 elements and I want to replace the second one at run-time. I do as follow:

...
   List newList = new ArrayList();
   List oldList = myObject.getList();
   MyElement newEle = new MyElement();
   ...
   oldList.remove(1);
   for(int i=0; i<oldList.size; i++){
      if(i!=1)
        newList.add(oldList.get(i));
      else
        newList.add(myEle);
   }
....

I find it's quite complecated. Someone has any other better way?
