Can I modify all global variables r,c in all entities to be named x,y and swap all r,c variable calls so that it corresponds to FishTank calls and draw/drawString methods? (x - width, y - height)
I did not change signature of setLocation or getX getY, but I did modify what they return or what they set. i.e. setLocation gets x,y from caller and set them as corresponding xy, getX returns x and getY returns y.
