参数的传递

Question

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；

Answer 1

整理下先.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);}
}
