如何将这个JScrollPane类添加到我的swing生成器中？

我试图将此类ScrollPaneDemo()与我的SwingBuilder组合在一起，但是以任何方式单独存在都会出现这种情况，因为我可以将两个组合在一起，以作为我读过反射的同一接口出现，但我不知道该如何使用。

如何将此类添加JScrollPane到我的挥杆生成器？

@Bindable
class Address { 
    String street, number, city
    String toString() { "address[street=$street,number=$number,city=$city]" }
}
class ScrollPaneDemo extends JFrame {

ScrollPaneDemo() {
    super("JScrollPane Demo");
    ImageIcon ii = new ImageIcon("pokemon.png");
    JScrollPane jsp = new JScrollPane(new JLabel(ii));
    getContentPane().add(jsp);
    setSize(300, 250);
    setVisible(true);
      jsp.addMouseListener(new MouseAdapter() {
            @Override
            public void mousePressed(MouseEvent e) {
                System.out.println("Mouse X="+e.getY()+" Mouse Y="+e.getY());
            }
        });
  }}

  public static void main(String[] args) {
    new ScrollPaneDemo();
  }
