Java: split a List into two sub-Lists?

Question

What\'s the simplest, most standard, and/or most efficient way to split a List into two sub-Lists in Java? It\'s OK to mutate the original List, so no copying should be nece

Answer 1

A generic function to split a list to a list of list of specific size. I was missing this for long in java collections.

private List> splitList(List list, int maxListSize) {
        List> splittedList = new ArrayList>();
        int itemsRemaining = list.size();
        int start = 0;

        while (itemsRemaining != 0) {
            int end = itemsRemaining >= maxListSize ? (start + maxListSize) : itemsRemaining;

            splittedList.add(list.subList(start, end));

            int sizeOfFinalList = end - start;
            itemsRemaining = itemsRemaining - sizeOfFinalList;
            start = start + sizeOfFinalList;
        }

        return splittedList;
    }
