ThreadPoolExecutor线程池如何处理集合

ThreadPoolExecutor创建5个线程 现在有7000条数据 如何实现呢

public class ThreadPoolExample {
    public static void main(String[] args) {
        ExecutorService executorService = Executors.newFixedThreadPool(5); // 创建线程池，包含5个线程
        for (int i = 0; i < 7000; i++) {
            final int index = i;
            executorService.execute(new Runnable() {
                @Override
                public void run() {
                    // 任务代码
                    System.out.println("线程" + Thread.currentThread().getName() + "处理数据" + index);
                }
            });
        }
        executorService.shutdown(); // 关闭线程池
    }
}
