用ArrayList的subList方法做分页

        List<Integer> beforeList= new ArrayList<>();
        for (int i = 0; i < 100 ; i++) {
            beforeList.add(i);
        }
        //假如有一个list，元素个数100
        int current=1; //页码
        int pageSize=10; //每页显示的数量

        int totalCount=beforeList.size();
        int pageCount = (totalCount / pageSize) + ((totalCount % current > 0) ? 1 : 0);

        int start=(current-1) * pageSize;
        int end = current==pageCount ? totalCount : current * pageSize;

        List<Integer> updateList=beforeList.subList(start,end);
        System.out.println(updateList);
