Learning about concurrency in Java. The code samples will consist mostly of ideas from the book "Java Concurrency in Practice" by Brian Goetz as I read through it. Also, I will add code samples based upon ideas that I have found from other sources and that I have came up by myself.

ThreadInterrupt --> One of the examples of how to interrupt a thread.
CancellingTaskUsingFuture --> Using Future to cancel task if it is not finished.
ExecutorShutdown --> Preferred way to shutdown executors.
TrackCancelledTasksAfterShutdown --> Example of how to track cancelled tasks after using .shutdown()
