线程池的使用（Runnable接口）

/**
 * 创建线程池
 */

public class test03ThreadExecutor {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ExecutorService executorService = Executors.newFixedThreadPool();  //创建线程池，中有三个线程对象
        MyRunnable1 myRunnable = new MyRunnable1();
        executorService.submit(myRunnable);
        executorService.submit(myRunnable);
        executorService.submit(myRunnable);
        executorService.shutdown();

    }

}
class MyRunnable1 implements Runnable{

    @Override
    public void run() {
        // TODO Auto-generated method stub
        System.out.println("我要一个教练");
        try {
            Thread.sleep();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("教练来了"+Thread.currentThread().getName());
        System.out.println("教练走了");
    }

}
