Answer / nisha
transient objects are the objects which lie in application
memory... once application is ended this object also get
vanished... whereas persistent objects have permanent
memory... they remain in memory untill they are xplicitly
removed....
transient objects cannot be converted to persistent objects
as they have their lifetime defined at the time of their
instantiation.

Answer / sarin
Persistent objects are on this heap, while transient
objects are in the transient memory. Transient and
persistent objects can access each other mutually.
Accessing a persistent object leads to loading the object
into the transient heap. It it is not accessed from
transient objects any more, it will be written back to the
persistent heap. A transient object becomes persistent as
soon as it can be reached from a persistent root
