如何在Java 7中使用线程池来实现任务的有序执行

import java.util.concurrent.*;

public class OrderedThreadPoolExample {

    public static void main(String[] args) {
        int threadPoolSize = 5;
        ExecutorService executor = Executors.newFixedThreadPool(threadPoolSize);
        
        for(int i = 1; i <= 10; i++) {
            final int taskNumber = i;
            executor.submit(new Runnable() {
                public void run() {
                    try {
                        System.out.println("Task " + taskNumber + " started");
                        // 模拟任务执行
                        Thread.sleep(1000);
                        System.out.println("Task " + taskNumber + " completed");
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            });
        }
        
        executor.shutdown();
    }
}
