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

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
讲解if语句之前先讲一下相关的运算符号 编程语言基本运算符号有: "<" ">" "==" "<=" ">=" "!=" 等 我挨个讲解他们的运算逻辑是怎么个实现的 首先是 ">" 运算符他的作用和数学上的 大于 相同,也是作为两个数的大小进行比较,如3>2,3肯定是大于2的,那么将会返回一个真条件,那如果是2>3,那么将会返回一个假条件,在c语言中,1代表真,0代表假,那么就是3>2返回1,2>3返回0 ">" 运算符和小于是相反的,和数学上面的比较方式类似 "==" 运算符在c语言中代表的是 "=" 打个比方就是1==1,将会返回一个真条件,就是1。如果是1==2那么将会返回0 另外的"<="以及">="同等与数学的 大于等于 和 小于等于。 "!=" 运算符表达的是不等于,也就是1!=1返回0,1!=2将会返回1。 上面是运算符------下面是if语句 if语句代表的就是c语言中的条件语句,写法: if(条件) { //条件为真后执行的代码区 } if语句中的条件值得就是上方的运算结果,打个比方: if(10>=9) { //条件为真后执行的代码区 printf("10>=9为真"); } 10>=9因为是正确的,最后会返回1,也就是真条件 接下来就是if中的else语句,写法: if(10>=9) { //条件为真后执行的代码区 printf("10>=9为真"); }else{ //条件为假后执行的代码区 printf("10>=9为假"); } else{}花括号中的代码在假条件时会被执行,但是10>=9是真条件,所以else花括号中的代码永远不会被执行 那么改成这样: if(10<=9) { //条件为真后执行的代码区 printf("10<=9为真"); }else{ //条件为假后执行的代码区 printf("10<=9为假"); } 因为10并不会小于等于9,所以条件为假,最后会执行的是else花括号中的代码,也就是printf("10<=9为假"); 最后就是else if()语句,这个语句代表的是:如果第一个if()中的条件未满足,那么将继续往下判断else if()中的条件是否为真: if(10<=9) { //条件为真后执行的代码区 printf("10<=9为真"); }else if(10>=9){ //条件为假后执行的代码区 printf("10>=9为真"); } 那么就是先判断10<=9是否未真,如果为真将会直接执行if(){}中的代码,如果为假,就会继续向下面的else if()中的条件进行判断是否为真,如果为真就执行else if()中的内容,如果为假则不执行。 当然if,else if以及else都是可以同时使用的: if(10<=9) { //条件为真后执行的代码区 printf("10<=9为真"); }else if(10>=9){ //条件为假后执行的代码区 printf("10>=9为真"); }else{ //上面条件全部为假 printf("上面条件全部为假"); } 这样写法就是当上面的if()以及else if()中的条件全部判断为假后将会执行else{}区块内的代码! ---最后是一点扩展内容--- c语言中的条件语句最后的结果都是0或者1,1==1最后会返回1,1==2最后会返回0,然而if()中写的条件最后也会变成0或者1。 if(1) { printf("条件为真"); } 那么这样写是不是也能执行呢?答案是可以的 我们可以写上两行代码来观测1==1最后返回的结果: int a = (1==1); printf("%d",a); 我这边调试最后打印的结果是1,也就是真条件。所以if()进行逻辑的判断

ASCII 打印字符 (字符编码: 32-127) 32~126(共95个)是字符:32是空格,其中48~57为0到9十个阿拉伯数字,65~90为26个大写英文字母,97~122号为26个小写英文字母,其余为一些标点符号、运算符号等。第127个字符表示的是键盘上的删除命令。 32-127ASCII码对应值在下方

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

需要使用Java中的Scanner类包: 在class上加入: import java.util.Scanner; 第二步骤就是将导入的包进行实体化调用: Scanner scanClass = new Scanner(System.in); 注意:这边只有 scanClass 是变量名称可以被更改,其他的都不可进行更改 最后就是调用这个类包: int input = scanClass.nextInt(); 这边的int是输入的参数为int整型 scanClass 是调用类的变量 完整代码示例: import java.util.Scanner; public class java20221216 { public static void main(String []args) { Scanner scanClass = new Scanner(System.in); /* 实体化类 */ System.out.print("请输入整数: "); float input = scanClass.nextInt(); System.out.println("输入的值为:" + input); } }
