java 线程池和lamda表达式

public class MyRunnable implements  Runnable {
    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName() + "卖票中");
    }
}

public class main {
    public static void main(String[] args) {
        //创建线程池
        ExecutorService t = Executors.newFixedThreadPool(2);
        t.submit(new MyRunnable());
        t.submit(new MyRunnable());
        t.submit(new MyRunnable());

        //lamda表达式，替代匿名类对象
        new Thread(() -> {
            System.out.println(Thread.currentThread().getName() + "执行中");
        }).start();

        //销毁线程池
        t.shutdown();
