System.out.println(3/5) = 0；System.out.println(2/5) = 0；System.out.println(4/5) = 0；System.out.println(6/5) = 1；System.out.println(7/5) = 1；System.out.println(8/5) = 1；System.out.println(11/5) = 2；System.out.println(12/5) = 2；System.out.println(13/5) = 2； |
结果等于得到的整数（商的整数）

System.out.println(17%5) = 2;System.out.println(16%5) = 1;System.out.println(13%5) = 3;System.out.println(8%5) = 3;System.out.println(7%5) = 2; |
结果等于余数（剩余多少）

System.out.println(2%5) = 2;System.out.println(7%8) = 7;System.out.println(6%8) = 6; |
取余（取模）有个规律就是：左边小于右边，结果为左边，左边大于右边，看余数
