java8创建线程：

 public static void main(String[] args) {
        Runnable rannable = () -> {
            try {
                TimeUnit.SECONDS.sleep(5);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            System.out.println("runnable run");
        };
        rannable.run();
        System.out.println(1111);
    }
