Judging from that statement I would say you need to take a step back fromd games and try to learn Java first. That is of a multi deminsional array type, which pretty much means it holds a bunch of references to blocks of memory (your objects). This is basic coding though, and I highly stress you stop trying to make a game and spend the time to learn programming first. You're only hurting yourself right now.
LOL. Actually i know java very well. I was asking what data type is it. Sprite, int, etc. ;-) I am fully aware of what an array is. This is like my 5th game. Just not sure how the match-3 thing works.
@Siesmic how do you go about updating the occupants each frame?
