Java键盘录入

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); } }

ASCII 打印字符

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

Uni-App学习:Vue中v-bind用法

v-bind主要用于绑定一个或多个属性值，或者向另一个组件传递props值。 <view v-html="html" :style="sty"> data() { return { sty: "background: red;color:#fff" } } 主要写法在上面所示完整写法是v-bind:style="sty"缩写::style="sty" 一般用于绑定标签属性

C语言数组定义解释

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

Uni-App学习:Vue计算属性computed

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

Uni-App学习:常用Vue记录

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"/> ...

Python基础:变量与数据类型

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）

Uni-App学习:父子组件传值

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
