Java tile based map | GameDev.net

Ok heres the problem, i am going through a "tutorial" with someone on another thread, but he is using a different way to paste the tiles and all that, this is what i thought it would be like( the way i want it) map[[1,1,1,1,1] 1,0,0,0,1 1,0,0,0,1 1,1,1,1,1]] with 1's being solid land and 0's being water.... so if someone can give me an example, that would be great HERE IS THE WAY IM DOING IT RIGHT NOW, WHICH HAS MANY EXCEPTION ERRORS **********************************************************************************
