By an interruptible method, we mean a blocking method that may throw InterruptedException, for example, Thread.sleep(), BlockingQueue.take(), BlockingQueue.poll(long timeout, TimeUnit unit), and so on. A blocking thread is usually in a BLOCKED, WAITING, or TIMED_WAITING state, and, if it is interrupted, then the method tries to throw InterruptedException as soon as possible.
Since InterruptedException is a checked exception, we must catch it and/or throw it. In other words, if our method calls a method that throws InterruptedException, then we must be prepared to deal with this exception. If we can throw it (propagate the exception to the caller), then it is not our job anymore. The caller has to deal with it further. ...
