Honestly, I'm not sure I understand what is being asked here: In the drawScene() method, call the setCellColor(int, int, Color) method for each cell of the playing field with the following arguments: x and y coordinates of the cell and any color (for example, Color.BLACK). I thought just had to call the drawScene method and pass integers and the color to the method...but it's failing validation, so I don't really know what it's asking for then?
