Java - split array list into 2 lists with ArrayList.subList() method

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
