class Panel1 extends Panel{
int i;
SearchImage si = new SearchImage();
final Image image=Toolkit.getDefaultToolkit().createImage(si.ll.get(i).getAbsolutePath());
Panel1(){}
Panel1(int i){this.i = i;}
public void paint(Graphics g){
System.out.println(i);

g.drawImage(image,0,0,image.getWidth(null),image.getHeight(null),null);

}

}

class ListMoniter extends MouseAdapter{
Panel p2;
int i;
ListMoniter(Panel1 p2){this.p2=p2;}
public void mouseClicked(MouseEvent e){
i=((List)e.getSource()).getSelectedIndex();
new Panel1(i);
p2.repaint();
System.out.println(i);

}
}
为什么下面的i传不到是面去；
