Python基础:循环语句

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

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

C语言基础: 逻辑运算符

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。

Java StringBuilder基本用法

//StringBuilder类型示例 public class demo3 { public static void main(String[] args) { //StringBuilder 定义的数据是可改变的 //String 定义的数据是不可改变的，每次覆盖都会产生新的变量 StringBuilder strb1 = new StringBuilder("1123"); //必须使用new方法进行赋值，数据存储在堆中 strb1.append("abc"); //使用append在str1后面添加新的数据，类似一个伪数组同样可以通过charAt的方式访问索引 System.out.println(strb1.charAt(5)); //返回5索引的字符 System.out.println(strb1); StringBuilder strb2 = new StringBuilder("ceshi123"); strb2.reverse(); //容器内的数据进行翻转 String str = strb2.toString(); //StringBuilder类型转为String类型，返回String类型数据 System.out.println(strb2); System.out.println(str); } }

Java 使用截取隐藏手机号

//使用截取隐藏手机号中间部分 public class demo1 { public static void main(String[] args) { String phone = "18153468453"; String start = phone.substring(0,4); String end = phone.substring(7); String newPhone = start + "****" + end; System.out.println(newPhone); } }

Java final修饰的基本使用

//final修饰的方法: 表明方法是最终方法，不能被重写 //final修饰的类: 表面类是最终类，不能被继承 //final修饰的变量: 表面变量为常量，不能在程序中被重新赋值 public class Test { public static void main(String[] args) { Zi z = new Zi(); Fu f = new Fu(); z.getPi(); //调用Fu类中无法被重写的getPi方法 System.out.println("=========================="); z.sum(5,6); //调用子类中被重写的sum方法 System.out.println("=========================="); //变量使用final修饰后无法被修改，变成常量，常量单词一般全大写组成。单词之间使用下划线隔开 //常量类型为基本数据类型时，记录的值不能发生改成。byte、char、short、int、long、float、double、boolean //常量类型为引用数据类型时，记录的地址值不能发生改变，内部的属性值可以改变。 //如对象使用final修饰后，还是可以调用set方法修改对象中的属性 final int A = 10; // A = 12; //报错，因为A是常量。无法修改，在定义时就必须完成赋值 System.out.println(A); } } class Fu { public final void getPi() { System.out.println("我是被final修饰的getPi方法，位于Fu类中"); System.out.println("3.14159265358979323846"); } public void sum(int a, int b) { System.out.println("我是没被final修饰的sum方法，位于Fu类中"); System.out.println(a+b); } } class Zi extends Fu { //sum方法没有被final修饰，可以被重写 @Override public void sum(int a, int b) { System.out.println("我是没被final修饰的sum方法，位于Zi类中"); System.out.println(a+b); } //getPi方法被final修饰，不能被重写，报错 // @Override // public final void getPi() { // System.out.println("我是被final修饰的getPi方法，位于Fu类中"); // System.out.println("3.14159265358979323846"); // } }

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

Java多态的基本使用

//多态的其他使用 public class Test { public static void main(String[] args) { //a变量数据类型为Animal，是Dog类的父类型 //方法调用时: 编译看左边，运行看右边 //意思是进行编译函数的时候会先在左边的类型(Animal)中查找是否有这个方法，如果有再到右边的类型(Dog)中运行被重构的方法，如果未找到方法就会报错 //因为方法编译看左边的特性，如果调用方法时，左边类中没有，而右边类中有这个方法。因为编译看的是左边的类，所以右边的方法也无法被找到 Animal a = new Dog(); a.show(); //调用Dog中被重写的show方法 // a.eat(); 报错的代码，因为编译时在左边的Animal类中未发现这个方法 Animal b = new Cat(); b.show(); //调用Cat中被重写的show方法 //变量调用时: 编译看左边，运行也看左边 //如果左边的类中没有这个变量，那么这个变量将无法被找到 System.out.println(a.a); //a变量在Animal中可以被找到并编译，正常输出100 // System.out.println(a.b); //b变量在右边的Dog类中，无法被找到无法被编译，报错 System.out.println(b.a); ////a变量在Animal中可以被找到并编译，正常输出100 //======================================================================= //解决方法也很简单，直接转换为子类的数据类型即可 Dog d = (Dog) a; Cat c = (Cat) b; d.eat(); c.eat(); } } class Animal { //动物类 private String type = "动物"; int a = 100; public Animal() { } public Animal(String type) { this.type = type; } public String getType() { return type; } public void setType(String type) { this.type = type; } public void show() { System.out.println("动物类型为" + this.type); } } class Dog extends Animal { int b = 200; public Dog() { super("狗狗"); //调用父类构造函数 } public void eat() { System.out.println(super.getType() + "正在吃骨头"); } @Override public void show() { System.out.println("动物类型为" + super.getType()); } } class Cat extends Animal { int c = 300; public Cat() { super("猫猫"); //调用父类构造函数 } public void eat() { System.out.println(super.getType() + "正在吃猫粮"); } @Override public void show() { System.out.println("动物类型为" + super.getType()); } }

Java基础:数组讲解

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

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

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）
