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();
