模拟彩票程序，有一个抽奖池,里面有100000张彩票，每张彩票有编号（6位数字组成，不能重复），中奖金额，全国有500个彩票购买点，每个购买点卖出150张彩票，用进程的同步，保证购买彩票不能重复，随机生成10个中奖号码，显示彩票的中奖情况。写出以上Java代码并详细注释

在Java中编写模拟彩票程序，我们需要创建一个彩票类，定义彩票的基本属性，以及线程安全的购买彩票和中奖号码生成等功能。这里是一个简单的示例，使用了`java.util.concurrent`包来实现并发和同步：

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Random;

// 定义彩票类
class LotteryTicket {
    private int id; // 彩票编号
    private double prize; // 中奖金额
    private boolean isWinning; // 是否中奖

    public LotteryTicket(int id, double prize) {
        this.id = id;
        this.prize = prize;
        this.isWinning = false;
    }

    // 获取彩票信息
    @Override
    public String toString() {
        return "ID: " + id + ", Prize: " + prize + ", IsWinning: " + isWinning;
    }
}

// 抽奖池类
class LotteryPool {
    private static final int TOTAL_TICKETS = 100000;
    private List<LotteryTicket> tickets = new ArrayList<>();

    public void initialize() {
        for (int i = 0; i < TOTAL_TICKETS; i++) {
            LotteryTicket ticket = new LotteryTicket(i, generatePrize());
            tickets.add(ticket);
        }
        Collections.shuffle(tickets); // 随机排列彩票
    }

    private double generatePrize() {
        // 省略中奖概率计算部分
        return Math.random(); // 这里仅作为示例，实际应根据规则生成不同金额
    }

    // 同步购买彩票
    synchronized public void buyTicket(int purchasePoint, int numTickets) {
        if (numTickets <= tickets.size()) {
            for (int i = 0; i < numTickets; i++) {
                if (!tickets.isEmpty()) {
                    LotteryTicket ticket = tickets.remove(0);
                    System.out.println("Purchase Point " + purchasePoint + ": Bought Ticket ID: " + ticket.id);
                } else {
                    break;
                }
            }
        } else {
            throw new IllegalArgumentException("Number of tickets exceeds available tickets");
        }
    }

    // 公布中奖号码
    public synchronized void announceWinners(List<Integer> winningNumbers) {
        for (LotteryTicket ticket : tickets) {
            if (winningNumbers.contains(String.valueOf(ticket.id))) {
                ticket.isWinning = true;
                System.out.println("Ticket ID " + ticket.id + " is a winner!");
            }
        }
    }
}

public class Main {
    public static void main(String[] args) {
        LotteryPool lotteryPool = new LotteryPool();
        lotteryPool.initialize();

        // 创建500个购买点
        for (int i = 1; i <= 500; i++) {
            Thread purchaseThread = new Thread(() -> {
                lotteryPool.buyTicket(i, 150);
            });
            purchaseThread.start();
        }

        // 生成10个中奖号码并宣布
        List<Integer> winningNumbers = generateWinningNumbers(10);
        lotteryPoolannounceWinners(winningNumbers);

        // 保证所有购买完成后再展示剩余未中奖彩票
        while (!lotteryPool.tickets.isEmpty()) {
            System.out.println("Remaining Tickets:");
            for (LotteryTicket ticket : lotteryPool.tickets) {
                System.out.println(ticket);
            }
        }
    }

    private static List<Integer> generateWinningNumbers(int num) {
        Random random = new Random();
        List<Integer> winners = new ArrayList<>();
        for (int i = 0; i < num; i++) {
            winners.add(random.nextInt(TOTAL_TICKETS));
        }
        return winners;
    }
}

在这个示例中，我们首先初始化彩票池，然后创建500个购买点的线程分别购买彩票。同时，我们生成10个中奖号码，并在主函数结束前检查是否有未售出的彩票。注意，这里简化了购票过程，实际应用中需要更复杂的错误处理和同步机制。
