LGTM 👍

Although there is another way to avoid the InterruptedException exception to resolve this problem, which is to replace shutdownNow() with shutdown() in the close() method. However, it might lead to an inability to exit normally. Therefore, it is necessary to use awaitTermination() to wait for a period of time, and still inevitably call the shutdownNow() method. Hence, current solution that does not change the previous behavior might be a not bad option so far 😄
