What happens to the locks if the JVM takes thread from running to runable?

[Marc Wentink]

I've read what certain methods that change the threads state do with the locks. Wait gives up the locks, sleep and yield do not. But what happens to the locks a thread has if the JVM takes it out of running and into the runnable state? It keeps them I guess, to get on running like it was running if the JVM puts it in the running state again?

I doubt moving from running to runnable would do anything to the locks. Runnable means that the thread has everything it needs and is ready for running when ever the scheduler decides to start execution. And that includes locks.

Small addition. wait gives up the lock on the object, on which wait is called. All other locks are still held by the thread.
