hi,, i am very much confused about how finalize() method works since there is very less explanation about this method.
can anyone help me out in explaining that in the following the defined object is eligible for garbage collection, If it is, how? and if not why? or will it ever be able to get collected by garbage collector as there exists a live ref reffering to the object.. please help in explaining the story behind the scenes..


thanks.
regards.

Hi arpit,

finalize() method is using to declare codes that needs to run before some object delete from memory by the garbage collector. But it's not guaranteed whether finalize() method runs or not by GC. Because Garbage collectors actions are unpredictable.

If we manually invokes finalize() method form some object therefor garbage collector will not invoke finalize() method when it delete that object.
But if we not invoke finalize() method manually and we add code into finalize() method that pass reference to that object into another objects reference variable we can protect that objects deletion at least once.

It's not happen because of a miracle in finalize() method. It happens because it's passed reference to this object into another object. Then garbage collector knows that and avoid deletion of that object because garbage collector is not delete objects that have references.

I think I explain it correctly..
