Simple Array Question

Newbie & Debugging Questions
#1

Does

int x;

use the same amount of memory, as

int[1][1][1][1][1] x;

?

#2

No.

#3

this is an object int[][][][][] pointing to the object int[][][][] pointing to the object int[][][] pointing to the object int[][] pointing to the object int[] pointing to a primitive int

#4

I have a class in which I have an
Object[][]

because there are cases in which both dimensions are used and some cases in which the second dimension is just 1
I thought this was a better solution than to kinda declare
Object a[]
and
Object b[][]
and do some ifs, because I hoped my solution would use less memory

and yea I should note that this is a performance critical class, so its should be done the best way.

#5

You could always flatten the array (assuming you know the dimensions at creation time).

#6

how does that work exactly ?

#7 

Object[width][height]

becomes

Object[width*height]

where an access like:

Object[i][j]

becomes

Object[i*arrayWidth+j]
#8

ah, clever.

thanks
