Get blank screen each time? tic tac toe GUI...

Question

I get a blank screen each time i run this...I'm trying to display a tic tac toe board...the x's and o's are randomly generated...any idea why it's blank each time??
public class TicTacToe extends JFrame
     private ImageIcon x = new ImageIcon("cross.gif");
     private ImageIcon o = new ImageIcon("not.gif");
     Random random = new Random(2);
     public TicTacToe()
          setLayout(new GridLayout(3,3));
          for(int y = 0; y<= 9; y++)
            Random r = new Random(2);
               int randint = r.nextInt();
               if (randint == 0)
                    add(new JLabel(x));
               if (randint == 2)
                    add(new JLabel(o));
     public static void main(String args[])
          TicTacToe frame = new TicTacToe();
          frame.setTitle("Tic Tac Toe");
          frame.setSize(450,450);
          frame.setLocationRelativeTo(null);
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.setVisible(true);
}

Interested, what was wrong?He used Random and random.nextInt() incorrectly. Given that nextInt() without arguments can return any int between Integer.MIN_VALUE and Integer.MAX_VALUE with equal probability, the chance of hitting 0 or 2 is fairly low. So, most times (for most Random seeds), his code would never add any buttons to the panel. And, actually, since he used a '2' to seed the Random generator, he always got the same sequence of "random" numbers every time. So, his code would always give the same 9 numbers, and, apparently, those numbers don't include either 0 or 2.
By the way, rollarace, besides picking the proper nextInt(...) method [you want the one that requires a parameter, as I assume you figured out], you should create the Random object once BEFORE the loop starts, and then just reuse it.
Also:
for(int y = 0; y<= 9; y++)should be:
for(int y = 0; y< 9; y++)Otherwise, once the nextInt(...) part was fixed, he'd add 10 buttons.
