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

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

import java.util.Scanner; //统计字符串信息 public class demo2 { public static void main(String[] args) { System.out.println("请输入字符串"); Scanner sc = new Scanner(System.in); String input = sc.next(); int count = input.length(); //字符个数 int numberCount = 0; //数字计算 int smallCount = 0; //字母计算 int elseCount = 0; //其他字符 for (int i=0;i<count;i++) { char s = input.charAt(i); if((s >= 'a' && s <= 'z') || (s >= 'A' && s <= 'Z')) { //char类型的变量在参与计算或判断大小的时候会自动转为int类型，对应的值为ASCII码 smallCount++; }else if(s >= 48 && s <= 57) { //48 - 57 在ASCII码中对应0-9，s在判断大小时会自动转为ASCII码 numberCount++; }else { elseCount++; } } System.out.println("总字符数量:" + count); System.out.println("数字数量:" + numberCount); System.out.println("字幕数量:" + smallCount); System.out.println("其他字符数量:" + elseCount); } }
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); } }
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
import random def create(): randomArr = [] while len(randomArr) < 6: randNumber = random.randint(1,33) if not randNumber in randomArr: randomArr.append(randNumber) randomArr.append(random.randint(1,16)) return randomArr def getUserInput(): userInput = [] while len(userInput) < 6: red_input = input("请输入第%d个红色球号码: " % (len(userInput)+1)) if red_input.isdigit(): red_input = int(red_input) if red_input >=1 and red_input <= 33: if not red_input in userInput: userInput.append(red_input) else: print("这个号码已经被选过了") else: print("请输入1-33之间的红球号码") else: print("请输入正确的号码") while len(userInput) < 7: blue_input = input("请输入蓝色球号码: ") if blue_input.isdigit(): blue_input = int(blue_input) if blue_input >=1 and blue_input <= 16: userInput.append(blue_input) else: print("请输入1-16之间的蓝球号码") else: print("请输入正确的号码") return userInput def getRedCount(arr,userInput): redCount = 0 for i in range(len(arr)): if arr[i] == userInput[i]: redCount += 1 return redCount def getBlueCount(arr,userInput): blueCount = 0 if arr[len(arr)-1] == userInput[len(userInput)-1]: blueCount = 1 return blueCount def getResult(redCount, blueCount): if(redCount == 6 and blueCount == 1): return "一等奖，中奖1000万" elif(redCount == 6 and blueCount == 0): return "二等奖，中奖500万" elif(redCount == 5 and blueCount == 1): return "三等奖，中奖3000" elif((redCount == 5 and blueCount == 0) or (redCount == 4 and blueCount == 1)): return "四等奖，中奖200元" elif((redCount == 4 and blueCount == 0) or (redCount == 3 and blueCount == 1) or (redCount == 2 and blueCount == 1)): return "五等奖，中奖10元" elif((redCount == 1 and blueCount == 0) or blueCount == 1): return "六等奖，中奖5元" return "未中奖" #创建中奖号码 arrNumber = create() #得到用户输入 userInput = getUserInput() #计算红球中奖个数 redCount = getRedCount(arrNumber,userInput) print("红球中奖个数: ",redCount) #计算蓝球中奖个数 blueCount = getBlueCount(arrNumber,userInput) print("蓝球中奖个数: ",blueCount) #最终结果 result = getResult(redCount, blueCount) print("中奖号码为",arrNumber) print("你输入的号码为",userInput) print(result)

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
