Grid of circles...

Question

I was just wondering what would be the easiest (yet most efficient) way of creating a grid of circles? Like a grid layout of drawOvals. Is this possible?
I have only been taught GridLayout, FlowLayout and BorderLayout managers. The goal is to set each circle a specific colour when it is clicked.
I was thinking of creating an array but how could I do this and display the array with circles?
For example...
for (int i = 0; i < 42; i++)
   drawOval();
}Obviously I can't nest a paint method inside a for loop...so how else could it be done?
Thank you. :)

I'm nearly there!
for (int i = 0; i < circleTiles.length; i++)
                    gameCenter.add(CircleGrid);
                  }Then for the subclass...
public class CircleGrid extends JPanel implements MouseListener
        boolean ifRed;
        public CircleGrid()
          ifRed = true;
          addMouseListener(this);
        public void toggleColor()
          ifRed = !ifRed;
          repaint();
        public void paintComponent(Graphics g)
          if (ifRed)
            g.setColor(Color.RED);
          else {
            g.setColor(Color.BLUE);
          g.drawOval(0, 0, this.getWidth(), this.getHeight());
        public void mousePressed(MouseEvent evt)
           toggleColor();
        public void mouseClicked(MouseEvent evt)
        public void mouseReleased(MouseEvent evt)
        public void mouseEntered(MouseEvent evt)
        public void mouseExited(MouseEvent evt)
        {}I have the array declared as:
int [][] circleTiles = new int [7][6];Now the compiler is saying CircleGrid cannot be found.
