Wait() : This function takes parameters as milliseconds and
puts the thread in wait state for the desired time of the
programmer after time passes the execution starts again.

Sleep() : This function is also used for same purpose using
his function by java you can put a thread in sleep state
.sleep does not contains any parameters so the thread will
not be automatically start execution It needs a wake up
signal again which can be Notify().or other function are
also provided by java.

So the main difference in Wait() and sleep() is wait takes
time parameter and wait for specific time only and sleep
throws a thread in sleep mode for unspecified time.
