代码：

  public class StaticGoogleMap extends JPanel
    {
        private JLabel label;
        private JFrame frame;
        private ImageIcon icon;
        private URLConnection con;
        private URL url;




        public void init()
        {
            try 
            {
            url=new URL("http://maps.google.com/maps/api/staticmap?center=New+York,NY&zoom=14&size=512x512&maptype=roadmap&sensor=false");
            con = url.openConnection();
            con.connect();
            InputStream is = con.getInputStream();
            BufferedImage img=ImageIO.read(is);
            icon=new ImageIcon(img);
            label=new JLabel(icon);
            add(label);
            frame=new JFrame("Google Map");
            frame.add(this,java.awt.BorderLayout.CENTER);
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setLocationRelativeTo(null);
            frame.setSize(500,500);
            frame.setVisible(true);
            is.close();

            } catch (MalformedURLException e) 
            {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) 
            {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }
        public static void main(String[] args)
        {
            new StaticGoogleMap().init();
        }

    }
