Khalid Mock Exam Garbage collection

[Gaurav Chikara]

Hi All
there are few questions from Khaalid Mock Exam
Since answers are not provided I would be thnakful if you give your views
Which statements describe guaranteed behavior of the garbage collection and finalization mechanisms?
a.Objects are deleted when they can no longer be accessed thru any reference
b.finalize method be eventually be called on every object
c.finalize method will neverbe called more than once on every object
d. an object will not garbage collected as long as it is possible for an active part of program to access it thru a reference
e. Grabage collector will use mark and sweep algorithm
I would rate b,c,d but e is doubtful case though it uses
mark and sweep algorithm but is it for every platform
this is confusing

b) is wrong, because the finalize will called once at an object
definitly(here is eventually the tricky word)
c, d are correct,
e) false

But the finalize method could not be called at all...are you sure it is wrong?
