I'm trying to display a 3 x 3 grid made up of an array of 9 individual cell objects. I created two classes, one for each cell, and one for the whole board. So far, I can only display the board 'border'. When I try to invoke the method to draw each cell from the Board class, i get a null pointer exception error within the black dos window for some reason?? Would anyone care to take a look and give a little feedback? I would really appreciate it.
