線程池ExecutorService

ExecutorService才是真正的線程池接口

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
?
public class TestExecutors {
    public static void main(String[] args) {
        ExecutorService service= Executors.newFixedThreadPool(10);
?
        service.execute(new MyThread());
        service.execute(new MyThread());
        service.execute(new MyThread());
        service.execute(new MyThread());
?
        service.shutdown();
?
    }
}
class MyThread implements Runnable{
    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName());
    }
}
