java用继承简单模拟实现群主发红包，成员收红包

先创建父类用户

import java.util.Scanner;class  User{String name;int mymoney;int sendmoney;int number;public User() {}public User(String name, int mymoney, int sendmoney) {this.name = name;this.mymoney = mymoney;this.sendmoney = sendmoney;this.number = number;}//定义成员方法，获取成员数量public  int numberExact(){System.out.println("请输入红包的数量：");Scanner nu = new Scanner(System.in);number = nu.nextInt();return number;}//定义成员方法，发红包public void sendmoney(){System.out.println("发红包,请输入红包总金额：");Scanner mo = new Scanner(System.in);sendmoney = mo.nextInt();};//定义成员方法，收钱public void recivemoney(){System.out.println("我收到红包啦！");mymoney +=sendmoney;}
}

创建群主类

class Leadman extends User{//初始化public Leadman() {}public Leadman(String name, int mymoney, int sendmoney) {super(name, mymoney, sendmoney);}//定义成员方法，实现发红包public void  leadsendmoney(){int mymoney=100;super.sendmoney();super.numberExact();mymoney -= sendmoney;sendmoney = super.sendmoney/number;System.out.println("每个群成员可获取红包："+sendmoney);System.out.println("我的余额："+mymoney);};public static void main(String[] args) {System.out.println("我是群主我要发红包啦！");Leadman leads = new Leadman();leads.leadsendmoney();}
}

更好的思路应该这样分析
