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).

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

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