Is Random class thread safe?

Question

Is it valid to share one instance of the Random class between multiple threads? And to call nextInt(int) from multiple threads in particular?

Answer 1

The Random class is not set up for one instance to be used in multiple threads. Ofcourse, if you did this, likely you will increase the possibility of getting un-predictable and closer to random numbers. But since it is a pseudo-random generator, I cannot see why you would need to share an instance. Is there a more specific requirement?
