Don't forget to revalidate and repaint if adding or removing components from a container. I've modified your SSCCE, and have gotten rid of the need to use images to make it runnable by folks who don't have access to your image files (like me! ).
Changes are noted by the! Comments.

CurrentPlayer; } @Override public void mouseEntered(MouseEvent e) { } @Override public void mouseExited(MouseEvent arg0) { } @Override public void mouseClicked(MouseEvent arg0) { } @Override public void mouseReleased(MouseEvent e) { } } Also class names should be capitalized, and also you should again make your ImageIcons once. Again, one ImageIcon can be shared by many JLabels.
You'll also want to respond to mousePressed not mouseClicked as mouseClicked can be fussy, especially if you move the mouse between press down and mouse release. Hopefully you've also seen the value of an SSCCE. :).
A minor non-programming suggestion - name the squares by a letter A-H (for the column) and a number 1-8 (for the row). E.g. The White King starts on E1.
Just like in real chess. – user949300 Nov 7 at 1:22 Actually the game I think the OP is creating is Reversi, not Chess, but the naming of the ranks and files is the same as in chess if my memory serves me right. – Hovercraft Full Of Eels Nov 7 at 1:25 for posting SSCCE – mKorbel Nov 7 at 8:20.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
