废话不多说直接上代码！

public static void main(String[] args) {
        List integers = Arrays.asList(1,2,3,4,5,6,7,8,9);
 
        List> chopped = chopped(integers, 5);
 
        for (List integerList : chopped) {
            System.out.println(integerList);
        }
 
    }
 
    // chops a list into non-view sublists of length L
    static  List> chopped(List list, final int L) {
        List> parts = new ArrayList<>();
        final int N = list.size();
        for (int i = 0; i < N; i += L) {
            parts.add(new ArrayList<>(
                    list.subList(i, Math.min(N, i + L)))
            );
        }
        return parts;
    }
