Mysql外链约束规则
java的mvc三层架构分别是： View(界面层),Service(业务逻辑层),DAO(数据访问层) V：View 网页视图，为用户提供能够看到并且使用的界面，与用户直接进行交互。 M：Model，业务模型，处理业务 C：Controller，控制器，处理请求，调用模型和视图 dao层负责对数据进行直接操控，最底层 service层负责对传递过来的参数验证，以及其他逻辑验证操作。验证完毕访问dao层进行数据操控 servlet层负责接收参数，然后调用service层进行处理 三个层分工合作，有利于后期的功能维护，那层出了问题就去处理哪层

基本的逻辑比较运算符在前面笔记说过了 链接:http://notei.cn/note_see/64 这里主要是讲 与运算 或运算 非运算 学过一点电子逻辑门都应该有点概念的 与运算在C语言中用的符号是 "&&" 实际用法就是: if(10>=5 && 6<=5)，顾名思义与逻辑就是要让两个逻辑同时为真最后才能返回真条件，反之就是假条件。 最后会返回的结果为0，为什么10>=5明明是真条件为什么会等于0呢？是因为6<=5是假条件导致整个运算结果也为假条件。 也可以多个条件一起进行运算if(1==1&&2==2&&3==3)多个条件一起运算也是可以的，如果三个条件都为真，那么最后会返回一个真条件，反之假条件。 或逻辑运算方式为只要有一个条件为真，那么最后就会返回真条件。反之全部为假条件，最后也只能返回假条件。符号为 "||" 用法为:if(1==1||2==3)。 非逻辑就是在条件的前面加一个 "!" 也就是小写的感叹号，让最后的逻辑取反。如果逻辑为真后加一个"!"条件将会变成假条件，反之为真。
在component目录下新建一个子组件 然后在父界面使用import绑定子界面: import child from "../../component/child.vue" child 是子组件名，from后面连接组件路径 然后使用components绑定组件: components: { child } 父传子参数可以通过标签属性传递: <child :content="content"></child> 子组件接收方法: props: ["content"] 子组件传递参数给父组件: 可以使用this.$emit通过事件的方式传递参数: but:function() { this.$emit("buts",this.putInfo); } buts 父组件接收的事件名， putInfo 是传递的参数 父组件通过标签属性的方式得到传递的参数: <child @buts="buts"></child> 夫组件通过buts事件接收 约束传递的参数: props: { content:{ type: [Number,String], } } 允许Number类型和String类型
//使用截取隐藏手机号中间部分 public class demo1 { public static void main(String[] args) { String phone = "18153468453"; String start = phone.substring(0,4); String end = phone.substring(7); String newPhone = start + "****" + end; System.out.println(newPhone); } }
如果我们想通过一个成绩来得到等级: <span>{{ author.chengji >= 85 ? '优' : '良' }}</span> 可以在标签内渲染一个计算结果达到目的，不过这样会导致运算代码和其他标签内容混淆看起来很臃肿，我们可以通过Vue的计算属性computed来达到分开计算的方法: computed: { chengji:function() { return this.chengji >= 85 ? '优' : '良'; } } ><span>{{ chengji }}</span> 计算属性值会基于其响应式依赖被缓存，如果计算的参数没有发生改变，那么就会直接调用缓存中的结果，而不用再次调用函数获取结果 如果使用methods方法来计算的话，每当数据改变时页面会重新渲染，全部函数将全被执行

常见的进制： 二进制 binary -----> bin 八进制 octal -----> oct 十进制 decimal -----> dec 十六进制 hexadecimal -----> hex php提供了几常见进制之间转换的函数 二进制转为其他进制 binoct();//转为八进制 bindec();//转为十进制 binhex();//转为十六进制 八进制转为其他进制 octbin();//转为二进制 octdec();//转为十进制 octhex();//转为十六进制 十进制转为其他进制 decbin();//转为二进制 decoct();//转为八进制 dechex();转为十六进制 十六进制转为其他进制 hexbin();转为二进制 hexoct();//转为八进制 hexdec();//转为十六进制 上面列举了这么多，其实自己感觉一点用没有，对于上面的这些函数，你只需要记着bin、oct、dec、hex就可以了，你要把a进制转为b进制，那就是ab() 举个简单的例子： 把二进制(bin)转为十进制(dec): bindec(); 但这样可能还不能满足我们的需求，于是php有个我们提供了一个真正实现爱咋转就咋转的函数：base_convert(); base_convert() 该函数有三个参数 string base_convert ( string $number , int $frombase , int $tobase ) 举个列子： hexadecimal=′125458′;//十进制echobaseconvert(hexadecimal, 10, 5);//转为五进制

Java数组创建方式 完整格式:数据类型[] 数组名 = new 数据类型[] {数组内容} 比如:int[] arr1 = new int[] {12,34,532}; 这样就定义了一个完整的数组格式 另外也可以用简写:int[] arr1 = {12,34,532}; 另外还有动态初始化的方式创建数组 完整格式:数据类型[] 数组名 = new 数据类型[数组类型] 比如:int[] arr1 = new int[3]; arr1[0] = 13; arr1[1] = 14; arr1[2] = 15; 先将数组动态创建完成，后期再进行输入录入 详细点的讲解可以看:http://notei.cn/user/note_see/60

一维数组定义方式为: int a[] = {0,1,2,3,4,5,...}; 或 int a[3] = {0,1,2}; 第一种定义方式没有指定元素数量，第二种固定三个元素进行传参，如果int a[4] = {0,1,2};，那么第四个元素默认是0 二维数组定义方式为: int a[][] = { {1,2,3}, {4,5,6}, {7,8,9} }; int a[][] 代表的是 要定义一个二维数组，=后面的值为二维数组的内容 a[0]输出结果为数组{1,2,3}，a[1]输出结果为数组{4,5,6}，那么a[0][1]输出为1，a[1][1]输出为4，a[1][1]输出为5 ----------以上是我觉得的---------- 和我学的PHP JS等语言不太一样的数组处理方式，深层逻辑我也不懂。 就以我学的PHP来说，PHP的数组定义: $a = []; 就是定义一个空数组 $a[] = 123; 就是将变量a数组的首个元素指定为123 $a[] = 123;$a[] = 456;将0键值的数据指定为123，将1键值的数据指定为456 --上面是PHP定义一维数组的基本方法-- PHP二维数组的定义方式和C语言也有一样的地方: $a = [ [1,2,3], [4,5,6], [7,8,9] ]; 定义和C语言一样的二维数组 当然也有不一样的地方: $a[0] = [0,1,2]; $a[1] = [3,4,5]; $a[2] = [6,7,8]; 这样定义出来也是一样的二维数组 ----------下面为我个人理解---------- 首先C语言的int a[][] = {{},{}}格式和PHP的$a = [[],[],[]]类似 int a[][] 代表的是 告诉系统要定义一个二维数组，=后面的值为二维数组的内容 而PHP可以直接指定一维数组的键值等于另外一个数组，从而达到二维数组的定义 只是自己做个笔记理解一下两个语言的数组定义方式以及不同，C我也是刚学不久不是很理解，就先写个笔记记录一下了

编写程序，从键盘输入列表，输出列表元素的平均值。其中平均值使用函数进行计算。 def get_input(): return input("请输入数据列表: ") def get_average(list): average = 0 for i in list: average += i average /= len(list) return average input_list = eval(get_input()) average = get_average(input_list) print(average)
