If an object is garbage collected can we retain it back or create a new object

You can create a new object at any point of time. But once an object is garbage collected it cannot be reclaimed. It is not even available in memory anymore.

You can create a similar object by persisting the Object's state but not have the same object back.

We can't tell when something is actually collected, so it's as gone as it's going to get as soon as it's eligible for garbage collection. Is that a useful nit-pick?

Since we're nit-picking, I'll point out that "it is possible and completely legal in Java to resurrect objects in finalizers -- to bring them back to life by making them referenced again." (Ref. JavaWorld - Object finalization and cleanup, under the heading Avoid finalizer abuse.)
