用 Java 写一个发红包程序

好的，下面是一个简单的 Java 程序，实现了发红包的功能。

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

public class RedPacket {
    private static final int MIN_MONEY = 1;
    private static final int MAX_MONEY = 200;
    private static final int NUMBER_OF_PEOPLE = 10;
    private int restMoney;
    private int restPeople;

    public RedPacket() {
        restMoney = MAX_MONEY * NUMBER_OF_PEOPLE;
        restPeople = NUMBER_OF_PEOPLE;
    }

    public ArrayList<Integer> splitRedPacket() {
        ArrayList<Integer> redList = new ArrayList<>();
        Random random = new Random();
        for (int i = 0; i < NUMBER_OF_PEOPLE - 1; i++) {
            int money = random.nextInt(restMoney / restPeople * 2 - MIN_MONEY) + MIN_MONEY;
            redList.add(money);
            restMoney -= money;
            restPeople--;
        }
        redList.add(restMoney);
        return redList;
    }

    public static void main(String[] args) {
        RedPacket redPacket = new RedPacket();
        ArrayList<Integer> redList = redPacket.splitRedPacket();
        System.out.println("红包金额分配情况：" + redList);
    }
}

该程序使用了随机数生成，将红包金额均分给每个人，并在控制台输出红包金额分配情况。
