Hello, I'm writing a chess game and have got the board drawn but I am having trouble painting the pieces on the board.

Below is my code for the white pieces:

import javax.swing.*;

public class WhitePieces extends JLabel {

        JLabel wPawn;
        JLabel wBishop;
        JLabel wKnight;
        JLabel wRook;
        JLabel wQueen;
        JLabel wKing;

        public JLabel wPawn() {
            wPawn = new JLabel(new ImageIcon("wp.gif"));
            return wPawn;
        }

        public JLabel wBishop() {
            wBishop = new JLabel(new ImageIcon("wb.gif"));
            return wBishop;
        }

        public JLabel wKnight() {
            wKnight = new JLabel(new ImageIcon("wk.gif"));
            return wKnight;
        }

        public JLabel wRook() {
            wRook = new JLabel(new ImageIcon("wr.giv"));
            return wRook;
        }

        public JLabel wQueen() {
            wQueen = new JLabel(new ImageIcon("wq.gif"));
            return wQueen;
        }

        public JLabel wKing() {
            wKing = new JLabel(new ImageIcon("wk.gif"));
            return wKing;
        }

    }

and this is the board painting part of the chess class:

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2 = (Graphics2D)g;
        g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                            RenderingHints.VALUE_ANTIALIAS_ON);
        
        double w = getWidth();
        double h = getHeight();

        double hInc = (w-1)/SIZE; //Horizontal Increment
        double vInc = (h-1)/SIZE; //Vertical Increment

        //Draw horizontal lines
        for(int i = 0; i <= SIZE; i++) {
            double x = i*hInc;
            g2.draw(new Line2D.Double(x, 0, x, h));
        }

        //Draw vertical lines
        for(int i = 0; i <= SIZE; i++) {
            double y = i*vInc;
            g2.draw(new Line2D.Double(0, y, w, y));
        }


        //Paint the board
       for (board_pointx = 0; board_pointx < SIZE; board_pointx++){
           for (board_pointy = 0; board_pointy < SIZE; board_pointy++) {

               double x = board_pointx*hInc;
               double y = board_pointy*vInc;
           
               g2.setPaint(LIGHT_COLOUR);
               g2.fill(new Rectangle2D.Double(x, y, hInc, vInc));

            if (board_pointx%2 == 0 && board_pointy%2 == 0) {
                g2.setPaint(DARK_COLOUR);
                g2.fill(new Rectangle2D.Double.Double(x, y, hInc, vInc));
                }

            if (board_pointx%2 == 1 && board_pointy%2 == 1) {
                g2.setPaint(DARK_COLOUR);
                g2.fill(new Rectangle2D.Double.Double(x, y, hInc, vInc));
                }
            }
        }

Any help would be great! Thanks
