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

首先常用的格式化输出有: 使用 % 占位符输出,常用的占用符可以在贴图中查看 用法: name = "Chumo" font = "My Name Is %s" print(font % (name)) 这里用的是%s字符串占位符,string的首字符s 使用%d输出整数: age = 19 font = "今年%d岁" print(font % (age)) 多个参数用法: name = "Chumo" age = 19 font = "我是%s今年%d岁" print(font % (name,age)) 上面就是基本的占位符输出用法 接下来就是使用 format 格式化 用法: age = 19 font = "今年{}岁" print(font.format(age)) 扩展:使用位置和关键字参数 print('我的名字是 {0}, 我的年龄是 {1}'.format(name,age)) print('我的名字是 {name}, 我的年龄是 {age}'.format(name="Chumo",age=18)) 上面是基本的format格式化输出方法 然后是 f-string 格式化输出方法 用法: name = 'chumo' age = 18 print(f'我的名字是 {name}, 我的年龄是 {age}') 要注意print函数中的 f 字符,在输出内容前加一个f字符,就可以直接将变量在字符串中调用{name} 上面是三种常用的格式化输出变量方式 接下来就是输出字符保留N位小数点方式: 首先说的是 % 占位符输出保留小数点的写法,首先保留小数点肯定是需要一个浮点型的数据,这边浮点数据用的是%f也就是float的首字符f来表示: name = 'chumo' age = 18.43 print(f'我的名字是 {name}, 我的年龄是 %f' % (age)) 输出结果为:我的名字是 chumo, 我的年龄是 18.430000 默认是保留小数点后面6位数据,怎么让他只保留两位呢? 我们可以用 %.2f 的方式保留两位小数: name = 'chumo' age = 18.43 print(f'我的名字是 {name}, 我的年龄是 %.2f' % (age)) 最后输出的结果为:我的名字是 chumo, 我的年龄是 18.43 想要保留更多小数可以在%.2f中修改数字大小来实现:%.3f就是保留三位 接下来就是format函数保留小数点的方法: age = 18.43 print('我的年龄是{:.2f}'.format(age)) 用的是 {:.2f} 保留两位小数的写法 前面的 : 符号是什么意思呢? 其实看下面这个例子就会知道: name = 'chumo' age = float(18.43) print('我的名字是 {name}, 我的年龄是{age:.1f}'.format(name=name,age=age)) 可以看到用的是{age:.1f}的方式输出保留小数点后一位 里面的 : 就是将 age 与后面的小数点长度区分开来 最后是第三种方法f-string格式化(python3.6以后的版本中可以使用) name = 'chumo' age = 18.43 age = round(age,1) print(f'名称{name}年龄{age}') 这种方法我前面介绍过了,是不需要区分数据类型就可以直接进行输出的 需要用到 round 函数处理浮点数保留的位数

绑定Vue内容前需要先在Vue中的data函数中声明好需要绑定的数据 v-html 主要用于显示html标签内容 用法:v-html="html" v-bind 主要用于绑定标签属性内容 用法:v-bind:style="style" v-on 主要用于绑定标签点击时触发的函数事件 用法:v-on:click="clicks" v-if Vue中的标签判断语句,如果条件为true标签会渲染在页面,如果为false那么标签会被隐藏 用法:v-if="条件" v-for 用于将数组渲染成列表 用法:<view v-for="(item,index) in list">{{item}}---{{index}}</view> v-model 用于双向绑定数据 用法:<input class="inp" v-model="input"/> ...

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。

C语言逗号运算符: int a = 10,b = 20,c = 0; 设置a变量等于10,b变量等于20,c变量等于0 逗号运算符写法: c = (a++,b+=10,a+=b); 注意:一定要用括号将内容包起来 括号内的表达式会从左往右执行,最后c的值会等于最后一个表达式,也就是a+=b 那么c最后会等于什么呢?有的人以为a+=b不就是a=a+b,最后不就是30吗,最后返回的值却是41,别忘了前面还有两个表达式,分别是a++和a+=b,执行完前面两个表达式后,a将会等于11,b会等于30,那么最后a+b就是11+30=41 当整个都好运算符执行完成后,最后a=41,b=30,c=41 为什么a也会等于41呢?因为最后一个表达式a+=b就是a=a+b也会执行,那么a还是会等于a+b也就是41。 写好的代码参考: #include <stdlib.h> int main() { int a = 10,b = 20,c; c = (a++,b+=10,a+=b); printf("%d,%d,%d",a,b,c); return(0); }

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

Python定义变量的方法为: name = "chumo" age = 19 也可以同时定义: name,age = "chumo",19 两种方法定义都是一样的结果 定义变量时不需要像c语言以及java那样先声明数据类型再写入变量内容。 Python常见的数据类型有: Number(数字) String(字符串) List(列表) Tuple(元组) Set(集合) Dictionary(字典)
