1. Split ArrayList into 2 sub lists

List<Integer> list = new ArrayList<>(); // size 7
for (int i = 1; i <= 7; i++) {
    list.add(i);
}
List<Integer> subList1 = list.subList(0, 2); // size 2
List<Integer> subList2 = list.subList(2, 7); // size 5

System.out.println(list);     // [1, 2, 3, 4, 5, 6, 7]
System.out.println(subList1); // [1, 2]
System.out.println(subList2); // [3, 4, 5, 6, 7]

System.out.println("size " + list.size());     // size 7
System.out.println("size " + subList1.size()); // size 2
System.out.println("size " + subList2.size()); // size 5
