基于java实现简单发红包功能

本文实例为大家分享了java实现简单发红包的具体代码，供大家参考，具体内容如下

这个案例是普通红包，均分的，不是拼手气红包。

package nuc.edu.day01.demo05;


public class User {
  private String name;
  private Double money;

  public User() {
  }
  //显示当前余额
  public void show(){
    System.out.println(name + "当前的余额为：" + money);
  }

  public User(String name, Double money) {
    this.name = name;
    this.money = money;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public Double getMoney() {
    return money;
  }

  public void setMoney(Double money) {
    this.money = money;
  }
}

package nuc.edu.day01.demo05;

import java.util.ArrayList;


public class Manager extends User {
  public Manager() {
  }

  public Manager(String name, Double money) {
    super(name, money);
  }

  
  public ArrayList send(double totalMoney,int num){
    
    ArrayList redList = new ArrayList<>();
    
    double leftMoney = super.getMoney();
    if (leftMoney < totalMoney){
      System.out.println("抱歉，您的余额不足");
      return redList;
    }
    
    super.setMoney(leftMoney-totalMoney);
    
    double avg = totalMoney / num;
    for (int i = 0; i < num; i++) {
      redList.add(avg);
    }
    return redList;
  }
}

package nuc.edu.day01.demo05;

import java.util.ArrayList;
import java.util.Random;


public class Member extends User {
  public Member() {
  }

  public Member(String name, Double money) {
    super(name, money);
  }

  
  public void receive(ArrayList list){
    
    int index = new Random().nextInt(list.size());
    
    double money = super.getMoney();
    
    double delta = list.remove(index);
    
    super.setMoney(money+delta);
  }
}

package nuc.edu.day01.demo05;

import java.util.ArrayList;


public class Main {
  public static void main(String[] args) {
    Manager manager = new Manager("群主",300.00);
    Member a = new Member("A",0.00);
    Member b = new Member("B",10.00);
    
    manager.show();
    a.show();
    b.show();
    System.out.println("============");

    ArrayList redList = manager.send(52.00,2);
    a.receive(redList);
    b.receive(redList);
    
    manager.show();
    a.show();
    b.show();
  }
}
