Question

Hey so I have 3 threads which have certain conditions when they print out something. this works fine. What I want to do now is make the thread just before it outputs something to send it to sleep for random amount of ms. I was thinking using the math class but not sure how.

the random() should generate random double greater than or equal to 0.0 and less than 1.0 right ?

will I just write something like

Thread.sleep(random());

^ that doesn’t work though tried it

Answer 1

Thread.sleep() takes a long value not double. You would need a typecast here: –

Thread.sleep((long)(Math.random() * 1000));
