Object array

Question

e.g if we have one class books and we declare array

books[] my = new books [5];

my [0] = new book ();

what will this do???
can anyone explain

Answer 1

@mehdi but what is the purpose of doing this when my [0] is already an object?

Answer 2

@Ettienne thanks alot. that makes it crystal clear

Answer 3

still not sure if i get the point but its okay

Answer 4

You are reassigning the my[0] reference in the array to point to a new book.

The previous reference is overwritten, meaning the previous book does not now have any references pointing to it - it is now basically 'garbage' and the GC will collect it on its next GC cycle (i.e. run its finalizer and then delete it).

Answer 5

its because where my[0] should store
object can store in object array

Answer 6

just do it. 😇

Answer 7

your books array should be extends object and its will work successfully
