对 ArrayList 进行分页.

/**
     *  测试分页
     */
    @Test
    public void testPage() {
        int bulkSize = 2;
        List<Integer> dataList = new ArrayList<>();
        for (int i = 1; i <= 10; i++) {
            dataList.add(i);
        }

        int offset = 0;
        int currentPage = 1;
        int pageSize = dataList.size() % bulkSize + 1;
        while (currentPage <= pageSize) {
            offset = (currentPage - 1) * bulkSize;
            int max = currentPage == pageSize ? dataList.size() - offset : bulkSize;

            for (; offset < max; offset++) {
                System.out.println(dataList.get(offset));
            }

            currentPage++;
        }

    }
