如何控制线程(控制球速)？

import java.util.concurrent.*;

public class ThreadSpeedControl {
    public static void main(String[] args) {
        ScheduledExecutorService executor = Executors.newScheduledThreadPool(1);
        Runnable task = () -> {
            // 执行任务
            System.out.println("Task executed at " + System.currentTimeMillis());
        };
        executor.scheduleAtFixedRate(task, 0, 100, TimeUnit.MILLISECONDS);
    }
}

import java.util.concurrent.locks.*;

public class ThreadSynchronization {
    private static int count = 0;
    private static Lock lock = new ReentrantLock();

    public static void main(String[] args) throws InterruptedException {
        Runnable task = () -> {
            lock.lock();
            try {
                count++;
                System.out.println("Count: " + count);
            } finally {
                lock.unlock();
            }
        };

        Thread thread1 = new Thread(task);
        Thread thread2 = new Thread(task);
        thread1.start();
        thread2.start();
        thread1.join();
        thread2.join();
    }
}
