public class ThreadPoolTest {public static void main(String[] args) {BlockingQueue<Runnable> queue = new ArrayBlockingQueue<Runnable>(10000) ;System.err.println(Runtime.getRuntime().availableProcessors());ExecutorService executor = new ThreadPoolExecutor(Runtime.getRuntime().availableProcessors(),//核心线程池大小,开启多少个线程20,//最大线程池大小120L, //线程池中超过corePoolSize数目的空闲线程最大存活时间；可以allowCoreThreadTimeOut(true)使得核心线程有效时间TimeUnit.SECONDS, //keepAliveTime时间单位queue) ;//阻塞任务队列for(int i=0;i<100;++i){executor.execute(new MessageTask(i+""));}}}

public class MessageTask implements Runnable {private String message ;public MessageTask(String message) {this.message = message;}@Overridepublic void run() {System.out.println(Thread.currentThread().getName()+"---------->"+message);}}

总结：1. 类似ThreadPoolExecutor的还有 newCachedThreadPool、newFixedThreadPool、newScheduledThreadPool 和newSingleThreadExecutor;
