java 5 线程池

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class ThreadPoolTest
{
    public static void main(String[] args)
    {
        ExecutorService threadPool = Executors.newFixedThreadPool(3);
        
        for(int i = 0; i < 10; i++)
        {
            final String taskName = "task " + i;
            threadPool.execute(new Runnable()
            {
                public void run()
                {
                    System.out.println(Thread.currentThread().getName() + "-" + taskName);
                }
            });
        }
           threadPool.shutdown();
    }
}
