Why is thread interrupted?
If the targeted thread has been waiting (by calling wait() , or some other related methods that essentially do the same thing, such as sleep() ), it will be interrupted, meaning that it stops waiting for what it was waiting for and receive an InterruptedException instead.
What happens when you interrupt a thread?
When the interrupt method is called on a thread object that is currently blocked, the blocking call (such as sleep or wait) is terminated by an InterruptedException. When the blocking operation has returned, you need to call the interrupted method to find out if the current thread has been interrupted.
How does thread interrupt work?
interrupt sets this flag. When a thread checks for an interrupt by invoking the static method Thread. interrupted , interrupt status is cleared. The non-static isInterrupted method, which is used by one thread to query the interrupt status of another, does not change the interrupt status flag.
How do I stop all threads in Java?
