no i mean to say that if my class takes 1 mb of memory in total then for suppose 10 objects will there be an allocation of 10*1mb=10mb of memory??
hi all,

could anyone please explain that if i make 1000s of instances of the same class then how will the memory be allocated to the instances of the class( i mean to diffent parts of the class i.e methods and attributes ) ...... please help !!!
dear ranchers
i passed SCJP 1.6 with 80% , few days back. Although i read a lot of books , but probably the best book for the exam preparation is SCJP 1.6 by Kathy Sierra and Bert Bates. Thanks for the great book!!!

and i added the Thread.sleep(10000) to allow me to see that my finalize method has executed, otherwise its very difficult to see.

yes i understand what should happen here. i am trying to fill the memory with objects having no refrence, thus forcing the garbage collector to run and in turn execute the finalize method. But this doesn't happen. i do not understand why? can someone help?
hi! can anybody tell that why this program not printing "dead" but is rather throwing this exception after creating a few objects


this is a piece of code that complies and runs fine:

how is this happening?
we know that string objects are created once and have the same value through their lifetime!!

yes , but why will it call the finalize method while collecting the abandoned objects?
can anyone explain in greater detail what he's trying to say?
