求分页数的三种方式

int count = 201;
int pageSize = 200;// 求最大页数1
int maxPage1 = (count - 1)/pageSize +1;
System.out.println("maxPage1 " + maxPage1);// 求最大页数2
int maxPage2 = (int) Math.ceil((double)count/pageSize);
System.out.println("maxPage2 " + maxPage2);// 求最大页数3
int maxPage3 = count / pageSize;
if(count%pageSize>0){maxPage3++;
}
System.out.println("maxPage3 " + maxPage3);
