Thread.sleep() is static method which make current running
thread "not runnable" for specific time. Sleeping thread
doesn't release lock. It will transit to "ready to run"
state after specified time elapsed or other thread interrupts.
wait() can be call on shared object. Wait can be call only
if thread has lock. On calling thread it releases lock on
object and transit to "not runnable" state. It wake ups and
transit to "ready to run" state after other thread that got
lock call notify() or notifyAll() on shared object or call
interrupt().
