And I also want to talk about why I added this challenge. This is because of a problem that I ran into during Java development. When working in a multi-threaded environment, especially when using something like an executor service, sometimes exceptions are not caught. So if I were to have a catch statement to catch all the exceptions here, it wouldn't catch the ones that are thrown even though every single task is throwing an exception. So when you're working in a multi-threaded environment, you need to be pragmatic about handling your exceptions so that you find them when they occur in your code. To do that, you can use something called a future, which holds the result of an asynchronous task. So that would look like this. Future,…
