How do I get an array slice of an ArrayList in Java? Specifically I want to do something like this: 

ArrayList<Integer> inputA = input.subList(0, input.size()/2);
// where 'input' is a prepouplated ArrayList<Integer>

So I expected this to work, but Java returns a List - so it's incompatible. And when I try to cast it, Java won't let me. I need an ArrayList - what can I do?

Although this post is very old. In case if somebody is looking for this..

Guava facilitates partitioning the List into sublists of a specified size

List<Integer> intList = Lists.newArrayList(1, 2, 3, 4, 5, 6, 7, 8);
    List<List<Integer>> subSets = Lists.partition(intList, 3);
