if I change the declaration as:

Code: Select all

int a = 10;
		Integer[] aa = { 10, 20 };
		long l = 30;

		probe(a);
		probe(aa);
		probe(l); 

it produce output as:
In Integer
In Integer..
In Long

but my question is why probe(aa) print: In Integer..
while it can also print: In Object
as

Code: Select all

int[]aa = {10, 20} 

declaration because

Code: Select all

Integer[]aa

"aa" is also object.
