here answer is 2,4 how come 4....i read in khalid...that its not neccessary that for the object to be garbage collected u need to set the references to null...dont remember the exact sentence...whats the case with isolation islands..they have the object references but then also they are eligible for GC.
one more doubt ..like in the Which of the following statements are true?sort of questions would b there or else they mention how many to choose??
srikanth You are correct that you don't have to set references to null. I thank they were tring to say that garbage collection occurs when there are no longer any vaild reference pointing to the object. This can occur for reason other then setting the reference to null.
