public class Test2 extends JFrame {

    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    Container content = getContentPane();
    MyPanel mp = new MyPanel(new ImageIcon("C:\\duke.gif").getImage());
    content.add(mp, BorderLayout.CENTER);
    setSize(400,400);
    setVisible(true);
  public static void main(String[] args) { new Test2(); }
class MyPanel extends JPanel {
  Image image;
  public MyPanel(Image i) { this.image=i; }
  public void paintComponent(Graphics g) {
