query on sleep() method

[Sandeep Mukherji]

When we call sleep(), it causes the running thread to transit to a ready to run state. Does the sleep() call will also relinquish the lock on the object if it is invoked from a synchronized method?

By "Ready to run" state you are referring to a "New" state?
Sleep gets the thread into a TIMED_WAITING state.

(These thread states are defined in the enum java.lang.Thread.State)

No it does not.
