Java’s Future API was introduced in Java 5, and a Future is used as a reference to the result of an asynchronous computation. We previously explained and gave a lot of examples related to multi-threaded operations in Java, and in this video we further expand on this topic by tackling Completable Futures which were introduced in Java 8 and their main purpose was to handle the limitations of the Future class.

Hands down the best explanation of completable futures out there. You're a master at explaining difficult concepts

I wondered if you might have tackled it elsewhere, but when I attempt to use the .sleep() method, it says that an InterruptedException can be thrown. Now I can handle this by either adding it to the method signature, or use a try-catch block. Now when I use a try-catch block, there is a warning that it is not enough to simply ignore the exception that is thrown, it needs to be re-thrown or interrupted. I have used something along the lines of: ``` ... try { TimeUnit.x.sleep(y); } catch (InterruptedException e) { Thread.currentThread.interrupt(); } ... ``` Now I have no idea what the reason is behind this, and then when I have tried to throw the InterruptedException, it asks me to surround it in a try catch block inside the catch block. Not sure if this is thread specific, and if you covered it anywhere else, or able to cover it. Thanks in advance for any information.

First, you just gave me an idea for a video! Thanks :) And to briefly answer your question, yes what you are doing is the way to go, and that's because each thread has kind of an "interrupted" flag, and if you simply ignore the exception, the thread's interrupted flag will not be set, and it will continue executing as if nothing happened, or that thread won't be handled appropriately by other threads. By calling this method in the catch block, you are setting the interrupted flag on the thread that was interrupted, allowing other parts of your code to check it and handle the thread appropriately. Hope this partly answers it, and stay tuned for more videos!
