2. 运行结果：

   [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
   [11, 12, 13, 14, 15, 16, 17, 18, 19, 20]
   [21, 22, 23, 24, 25, 26, 27, 28, 29, 30]
   [31, 32, 33, 34, 35, 36, 37, 38, 39, 40]
   [41, 42, 43, 44, 45, 46, 47, 48, 49, 50]
   [51]
   

   
   
   
   

3. 每页显示

   说明：其中pagesize：每页显示多少个，start是第几页 需要作为参数传递进来，list下标从0开始，sublist方法第一个参数包含，第二个参数不包含

   list 为要分页的list集合，pageSize是每页数据条数，i 是第几页

4. private static List<CourseAllDTO> fenye(List<CourseAllDTO> list, int pagesize, int i) {
       int totalcount = list.size();
       int pagecount = 0;

       if (m > 0) {
           pagecount = totalcount / pagesize + 1;
       } else {
           pagecount = totalcount / pagesize;
       }
       System.out.println(pagecount + "-------");
       System.out.println(m + "----m---");
       List<CourseAllDTO> subList = new ArrayList<>();
       if (m == 0) {
           subList = list.subList((i - 1) * pagesize, pagesize * (i));
