一、使用方法，封装变量. 1 # 使用方法，封装变量. 2 class Wife: 3 def __init__(self, name, age, weight): 4 self.name = name 5 # 本质:障眼法(实际将变量名改为：_类名__age) 6 # self.__age = age 7 self.set_age(age) 8 # self.__weight = weight 9 self.set_weight(weight) 10 11 # 提供公开的读写方法 12 def get_age(self): 13 return self.__age 14 15 def set_age(self, value): 16 if 21 <= value <= 31: 17 self.__age = value 18 else: 19 raise ValueError("我不要") 20 21 # 提供公开的读写方法 22 def get_weight(self): 23 return self.__weight 24 25 def set_weight(self, value): 26 if 40 <= value <= 60: 27 self.__weight = value 28 else: 29 raise ValueError("我不要") 30 31 """

代码很简单，但算法很经典，话不多说，直接上代码。 public struct ServerConfig { /// <summary> /// 初始权重 /// </summary> public int Weight { get; set; } /// <summary> /// 当前权重 /// </summary> public int Current { get; set; } /// <summary> /// 服务名称 /// </summary> public string Name { get; set; } } 　　 public static int NextServerIndex(ServerConfig[] ss) { int index = -1; int total = 0; int size = ss.Count(); for (int i = 0; i < size; i++) { ss[i].Current += ss[i].Weight; total += ss[i].Weight; if (index == -1 || ss[index].Current < ss[i].Current) { index = i; } } ss[index].Current -= total; return index; } 　　 static void

我们搭建一个maven项目，然后我们加载数据，数据我已经准备好了。 -- truncate all delete from jpa_test . oo_t_idcard where 1 = 1 ; delete from jpa_test . oo_t_person where 1 = 1 ; -- oo_t_person INSERT INTO jpa_test . oo_t_person ( id , created_by , created_date , last_modified_by , last_modified_date , hair_color , height , weight ) VALUES ( 1 , 4 , '2019-12-12 02:55:14.786000000' , 4 , '2019-12-12 02:55:14.786000000' , 'green' , 62.00 , 75.00 ) ; INSERT INTO jpa_test . oo_t_person ( id , created_by , created_date , last_modified_by , last_modified_date , hair_color , height , weight ) VALUES ( 2 , 4 , '2019-12-12 02:55:14

继承的作用是减少代码冗余，通过协调来减少接口和界面。 1.派生类的定义 <1>吸收基类成员 <2>改造基类成员 一是依靠派生类的继承方式来控制基类成员的访问、二是对基类成员或成员函数的覆盖。 <3>添加新的成员 2.类的继承方式 <1>.公有继承 #include <iostream> using namespace std; class vehicle { private: float weight; int wheels; public: vehicle(int in_wheels,float in_weight) { wheels=in_wheels; weight=in_weight; } int get_wheels() { return wheels; } float get_weight() { return weight; } }; class car:public vehicle { private: int passenger_load; public: car(int in_wheels,float in_weight,int people=5):vehicle(in_wheels,in_weight) { passenger_load=people; } int get_passenger() { return passenger_load; } };

功能：=》大于1000用kg表示 小于1000，用g表示 计算属性 计算属性必须是有一个返回值的哦 在html写被计算的值 在computed中去直接调用哈 <view> <text>{{jisuweight}}</text> </view> data() { return { weight:1110, } }, computed:{ jisuweight(){ return this.weight>1000 ? (this.weight/1000)+"kg" : this.weight; } }, 来源： https://www.cnblogs.com/IwishIcould/p/12184430.html
