如何一次运行多个线程，每个线程增加一个计数器？

Question

我想模拟线程之间的竞争，但有些线程无法启动。如何以这样的方式实现run方法：每个竞争者线程增加一个Counter，当计数器达到值100时，获胜者线程在RaceContext中宣布。每个都有10个团队，每个团队有4个ThreadCompetitors ......这就是我到目前为止所做的：

种族：

public class RelayRace {
    private List<RelayRaceTeam> teamList = new ArrayList<>(10);

    public RelayRace() {
        teamList.add(new RelayRaceTeam("FERRARI"));
        teamList.add(new RelayRaceTeam("BMW"));
        teamList.add(new RelayRaceTeam("LAMBORGHINI"));
        teamList.add(new RelayRaceTeam("DACIA"));
        teamList.add(new RelayRaceTeam("NASCAR"));
        teamList.add(new RelayRaceTeam("OPEL"));
        teamList.add(new RelayRaceTeam("MITSUBISHI"));
        teamList.add(new RelayRaceTeam("HONDA"));
        teamList.add(new RelayRaceTeam("PORSCHE"));
        teamList.add(new RelayRaceTeam("MERCEDES"));

    }

    public void start() {
        teamList.forEach(RelayRaceTeam::start);
    }
}

TeamClass：

public class RelayRaceTeam extends Thread {
    private static final ThreadRaceContext context = new ThreadRaceContext();
    private ArrayList<RelayRaceCompetitor> competitors = new ArrayList<>(4);
    private String name;

    public RelayRaceTeam(String name) {
        this.name = name;
        for (int i = 0; i < 4; i++) {
            competitors.add(new RelayRaceCompetitor());
        }
    }

    @Override
    public void run() {

        competitors.forEach(RelayRaceCompetitor::start);

        for (RelayRaceCompetitor competitor : competitors) {
            System.out.println("Competitor " + competitor.getNumber() + " from team " +
                    name + " has traversed " + Count.getCounter());
        }

        if (Count.getCounter() == 100) {
            synchronized (context) {
                context.announceWhichTeamWon(name, competitors);
            }
        }
    }
}

竞争对手：

public class RelayRaceCompetitor extends Thread{
    private int number;
    private static final AtomicInteger count = new AtomicInteger(0);

    public RelayRaceCompetitor() {
        number = count.getAndIncrement();
    }

    @Override
    public void run() {
        Count.increment();
    }

    public int getNumber() {
        return number;
    }
}

宣布获胜者的背景：

public class ThreadRaceContext extends Thread {
    public void announceWhichTeamWon(String name, ArrayList<RelayRaceCompetitor> competitors) {
        System.out.println(name + " won the competition");
        for (RelayRaceCompetitor competitor : competitors) {
            System.out.println("Competitor number : " + competitor.getNumber());
        }
    }
}

柜台：

public class Count {
    private static int counter = 1;

    public static void increment() {
        counter++;
    }

    public static int getCounter() {
        return counter;
    }
}
