Hi,


I have some questions about accessing the object in the finalize () Method.


1.Who is responsible for calling the finalize () Method in java programs.

2.If JVM calls the finalize () Method ,then on which object the method is being called(its not a static method).Is it the same object which needs to be garbage collected?

3.If its the same object(which need to be GC),then is following statement is true?

The object cannot be garbage collected until and unless the finalize () Method is being called.

4.Can I reuse the object for which the finalize () method is runing ,so that to avoid its GC?

Thanks

1. JVM
2. Yes
3. Well sort of, the JVM might not be able to call finalize method on your object if the JVM session ends before your object is garbage collected.
4. Yes you can, you can assign the this reference to a static variable to create a reference for your object in which case it will not be garbage collected. But when it does, the finalize method would not be called again...
