Objects created on Heap

[ramya ray]

Please explain how many objects are created on heap in a multi dimension array.
for eg:

int [][]a = new int[3][]; //how many objects will be created on heap?
and for
int [][]a = new int[3][5]; //how many objects will be created on heap?

Please explain.
Thanks.

int [][]a = new int[3][]; //how many objects will be created on heap?

1 (A single array is created. That array is an object stored on the heap. The array has three null references.)

int [][]a = new int[3][5]; //how many objects will be created on heap?

4 (An array with references to three other arrays. Each array is an object on the heap.)
