Battleships game

[ragaman123]

Hello everyone,

I am currently working on a battleships game and at the moment i am playing around with a interface which has various different buttons. The interface has a 2d grid of buttons and other buttons on it which make various noises when pressed.I am however having problems changeing the icon of any of the buttons. Iv put up all the code of it, i am sorry for putting the whole thing up but thought maybe if i left some out someone mightn be abe to figure it out. There is aslo a simpleSoundPlayer class for playing the sounds, but im not putting this up. You can see in the final if statement in the actionPerformed method at the end i am using the setIcon method to try and change the icon of the JButton but it is not working! Any ideas as to why would be greatly appreciated!Once again, im sorry for putting up piles and piles of code hope im not annoying anyone!
Thanking you,
Ragaman.

Since you could not post code for the other class I won't be able to fully test your program but here is what I think:

After changing the Icon of the button, you need to reshow the frame again for the updated interface to reflect the icon change. Try to call setVisible(true); after changing the icon.

Thank you for your advise, i have tried using this however but still to no success.I think the problem is i have to get a reference to the button pressed in the actionPerformed method, and then use the setIcon and setVisible methods.However when i refer to a button in the actionPerformed method it is not the same button as in the main method.I will post the code for the sound player class, you also need the pictures and sounds, i will try put these up aswel.Any advice or helpful hints would be greatly appreciated,
Thanks a million,
