You might want to read the “prior art” section of their article…

Who's right though? The article seems to go directly against what parent said above?

> In Java, there’s a similarly looking thread interruption mechanism. Critically, it doesn’t support interrupting syscalls: IOException and InterruptedException are both checked and unrelated, meaning that IOing functions are not interruptible

One says IOing functions are not interruptible, other says "You can interrupt a blocking IO operation" :)

The article seems to talk about how `Thread.interrupt` works with synchronous IO, rather than the async IO machinery of `java.nio`. So I'd say the article is inaccurate or at least incomplete.

NIO can be blocking or non-blocking. Indeed you can switch between the two on a single channel.

Sort of.

The article just references Thread.interrupt
