    Well first of all thx for your time. I am making a game (applet) where i have 9 buttons.Eight of them got the numbers from 0-8 on them and there is one blank box. The objective of this game is to put them in order (1,2,3,4,5,6,7,8,blank). The thing is how do i make change position with the blank one. The thing is that only neighbouring buttons can swap. I have tried everythin but.. My main idea was to swap the 2 block from the arrays i use then panel.removeAll(); add them again validate and repaint the applet but i got a problem with swap,when i swap the to block of the array i want to swap end up with the same JButton. please help.

    One thought would be to change the contents of the JButtons instead of moving them around.
