public class DrawIcon implements Icon{
    private int width;
    private int height;
    public int getIconHeight() {
        return this.height;
    }

    }
   
    public DrawIcon(int width, int height) {
        this.width = width;
        this.height = height;
    }
   
    public void piantIcon(Component arg0, Fraphics arg1, int x, int y) {
        arg1.fillOval(x,y,width,height);
    }
   
    public static void main(String[] args) {
        DrawIcon icon = new DrawIcon(15,15);
        
        JLabel j = new JLabel("测试", icon,SwingConstants.CENTER);
        JFrame jf = new JFrame();
        Container c = jf.getContentPane();
        c.add(j);
        jf.setVisible(true);
        jf.setSize(500,300);
        jf.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    }
   
   

}
