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

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

Python常用的循环函数是 while 和 for 先说明while循环的格式 while 循环条件: 代码段 如: i = 10 while i > 0: i-=1 print(i) 将会依次打印出9 - 0 for循环也是类似: for 临时变量 in 目标对象: 代码段 如: for i in [0,1,2,3]: print(i) 将会打印出数据集内全部数据 当然也可以依次遍历字符串如: for i in "Python Go": print(i) 将会依次打印单个字符结果 死循环用法: while True: 代码段 另外可以用: while(循环条件) 以及 for(i in "Python")这种用括号包含条件的方法

Java方法定义格式为: public static void 方法名称(参数){...} 例如: public static void test_fun(){ System.out.println("我的第一个方法"); } 调用方法就是直接 test_fun(); 使用void创建方法是不能使用return来返回结果的 想要返回结果需要使用其他类型例如: public static int 方法名称(参数){... return int} 这样的写法就可以返回一个int参数,其他类型也是一样的例子 -------下面讲讲其他语言的方法定义方式------- 首先就说说PHP的方法定义: function 方法名(参数){...} PHP定义方法时不需要定义方法的数据类型,可直接使用return返回各个类型的数据 另外就是C语言,定义方式: void 方法名(参数){...} C语言也是和Java类似,也是需要再定义时决定数据类型才可以进行返回相应的数据类型,例如int 方法名(参数){...}这样就可以返回一个int类型的
