In particular when you're adding to an ArrayList, the array can be resized in advance. Growing arrays is often a big performance hit in Java programs. You only need to device some smart immutable collection that returns the right amount of nulls. My point was: when you are growing the list, you may want to use the potentially more efficient addAll.
