Noam Damri 3 initializing a 3 dimension array
Hey everybody.
Ive created a 3 dimension integer array, it's go like this:
List<List<List<integer>>> ArrayList = new List<List<List<integer>>>();
the thing is that i'm trying to approach cell directly, like that:
ArrayList[2][3][4] = 7;
and im getting:
FATAL_ERROR|System.ListException: List index out of bounds: 2
which i was guessing is because i havnt initialized the cell and tried to approach it directly.
ive run a 3 nested for loops in order to initialize the array using:
ArrayList.add(0);
but i kept getting the same message (this time: List index out of bounds: 0, of course)
so im a bit stuck and dont know how to deal with this array but im surely have to use it
suggestions will be welcomed!
Thanks in advanced,
Noam
