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

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

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

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。
如图快捷键
关于interrupt函数用法: void +函数名+interrupt +数字0~4 0 表示外部中断0 1 表示定时器/计数器(T0) 2 外部中断1 3 定时器/计数器(T1) 4 串行口 0 一般作为定时器中断使用 4 一般作为串口接收/发送数据 用法: void 函数名() interrupt 4
