Please Help! Changing a graphic via a menu with listeners

[nt5515]

hey Im trying to make a game of pairs (the memory game) i have set up a grid which displays a graphic for the card back. im trying to link the edit menu to choose the graphic to be displayed. i've set up a string variable called deck which will contain the path to the required image. and actionlisteners DA and DB corresponding to which style is choosen in the menu. I had to declare the deck to some initial image so it can load.
How do i impliment the change once the menuitem has been selected?
below is my code so far.

   {

      Filenew frame = new Filenew();

      frame.display();

   }

   public Filenew()
   {
      this(2, 2);
   }

   public Filenew(int x, int y)

   {
      setBackground(Color.red);

      New.add(New44);
      JMenuItem New54 = new JMenuItem("5x4");
      New.add(New54);

      Exit = new JMenuItem("Exit");

      filemenu.add(New);

      filemenu.add(Exit);

      JMenu editmenu = new JMenu("Edit");

      menubar.add(editmenu);

      editmenu.add(ChangeD);
      JMenuItem DA = new JMenuItem("Style 1");

   }
   public void newGame(int x, int y)
   {
      closeGame();
      gameFrame = new Filenew(x, y);
      gameFrame.display();
   }
   public void closeGame()
   {
      if (gameFrame != null)
      {
         gameFrame.dispose();
         gameFrame = null;
      }
   }

}

Any suggestion welcome

Call setIcon(yourNew IconImage) on the JLabel(s) whose image you want to change.
