Java – call thread Sleep () and * interrupt status * settings?

Java documentation is unclear at this point After calling thread What happens if an interrupt is called on a thread before sleep():

//interrupt reaches Thread here
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            return;
        }

Will interruptedexception be thrown?

Editor: if you know the answer, can you ask me to point out the relevant documents?

Solution

Yes, it throws an exception According to thread Javadoc of sleep, method:

In this case, 'has' is an informal way to refer to interrupt status It is a pity that if a specification should be precise and explicit, it is ubiquitous, but it is the thread primitive first

The working mode of interrupt state mechanism is that if a thread receives an interrupt without interruption (because it is running), the interrupt basically waits until the thread is interrupted. At this time, it will lead to a cause of interruptedexception This is an example of this mechanism
