after catching “InterruptedException”, why “Thread.currentThread().isInterrupted()”'s value is false?

Question

as the title.

public static void main(String[] args) throws InterruptedException {

    Thread thread = new Thread(new Runnable() {
        @Override

From the Javadoc for Thread.sleep (called by TimeUnit.sleep):

InterruptedException - if any thread has interrupted the current thread. The interrupted status of the current thread is cleared when this exception is thrown.

I think the intention of isInterrupted() is to allow you to detect whether a thread has been interrupted before calling something which would throw InterruptedException. If you've caught InterruptedException, it's fair to assume that the thread has been interrupted...
