Buttons Problem

[Coold0wn]

            for(int x = 0; x < 256; x++)
            {                
                imageIcons[x] =  new ImageIcon(images[x]);
                buttons[x] = new JButton(imageIcons[x]);
                
                buttons[x].setMnemonic(KeyEvent.VK_I);
                buttons[x].addActionListener(new ActionListener() {
                    public void actionPerformed(ActionEvent e) 
                    {
                        pickedTileSetzen(x); //needs an integer , but it doesnt work with x - cause its in the for() and thats not 'final'.
                    }
                });
                MainFrame.getContentPane().add(buttons[x]);
            }

i have 256 buttons and 256 ImageIcons.
the buttons should do the method pickedTileSetzen(int x).
the first button in the list should do pickedTileSetzen(0) and the last one pickedTileSetzen(255)
but it doesnt work if i put x in there, cause x would have to be final.
is there a trick with which i can solve that problem?
i dont want to do 256 buttons one after another.. thats why i use 'for'.

For a better trick create a single ActionListener that can be shared by all the buttons. Something like:

ActionListener al = new ActionListener()
{
    public void actionPerformed(ActionEvent e)
    {
        JButton button = (JButton)e.getSource;
        int index = Integer.parseInt(button.getActionCommand());
        pickedTileSetzen( index );
};

...

for (...)
{
    ...
    buttons[x].setActionCommand("" + x);
    buttons[x].addActionListener( al );
}
