Sorry, a complete beginner to java. I have done a square grid before, for a checkers game, however I am having trouble for a hexagonal grid. I followed the same idea of with the square grid however, I have small little dots on my JPanel, although I am not sure what is the reason for this, I have looked around and tried to see what could be wrong.

I could use a Square Grid to lay out the hex icons, but that defeats the purpose because I want the grid to align to each other
