small doubt

[krishnaa yadav]

when we creat a 1-D array how many objects are created on heap one or two..
eg : int [] dots={6,7,8}

[Avishkar Nikale]

For the given example since it is a 1-D primitive array it will create one object on heap.

Can you elaborate your doubt so that we can explain better ?

[krishnaa yadav]

the followin code can be written as
int[] dots;
dots = new int [3]

so if we draw a heap stack diagram it would be

2000 and 3000 assumed memory location

From line 1
------------
HEAP
2000:int[] arrobjct

STACK
2000:dots


From line 2
-------------
HEAP
2000:int[] arrobjct----->3000
3000:int[3]: 6 7 8(value would be assigned)

STACK
2000:dots

finally there are 2 objcts created one at 2000 location and other at 3000 location ....
if i am wrong please correct...

The first line only declares an array reference -- no objects are allocated (instantiated) at this time. Granted, if the variable is a local variable, then some space is allocated for it, but that doesn't make it an object.

With the second line, an object is instantiated. And the variable, declared earlier is referenced to it.
