Hi, Thank you at before.

Now I mean another problem.



I do sequential explanation.


First. the Virus Panel Clicked.



Second. that opposite add Green Ground(Y-95 location).

Third. Green Ground(in Y-95) was clicked by mouse.



Fourth. Virus Panel move Y-95(forward).



Fifth. the Link Panel Clicked.

Sixth. that opposite add Green Ground(Y-95 location).

Seventh. seem third. (Green Ground(in Y-95) was clicked by mouse.)



Eighth. Virus Panel move Y-95(forward)



originally, if Link Panel clicked by mouse, Link Panel go forward.

but Link Panel not moved instead of Virus Panel moved.

I think due final JPanel mvp. but, can't remove final.

The eclipes have necessary final.

so, I think. Not used final variable, error don't get out.

but it not possible. Used final variable, enable reset final variable or change value(address value) of final variable.

how to do?

  Virus.visible(true);
  Link.visible(true);
   Virus.addMouseListener(new MouseAdapter() {
    public void mouseClicked(MouseEvent e) {
     Moving mv= new Moving();
     mv.move_AE(Virus);
   }

   Link.addMouseListener(new MouseAdapter() {

     Moving mv= new Moving();
     mv.move_AE(Link);

}

class Moving{
 public void move_AF(JPanel mvp){
  if(!(Virus.getY()<=123)){
   move_N.setLocation(mvp.getX(), mvp.getY()-95); //Green Ground.
   move_N.setVisible(true);            
  }
 }
 public void move_AE(final JPanel mvp){
  move_N.addMouseListener(new MouseAdapter() {
   public void mouseClicked(MouseEvent e) {
    if(event){      
     move_set();

     mvp.setVisible(true);
     event=false;

Declaring a variable as 'final' does not matter here because you don't reassign it.
I can only guess that problem is in (member) variable 'event'.

code and image added so, you review.

And completely Green Ground do work.

but move_method don't well do.

So, I think, have a problem with 'final'

Do you really want to add new listener on every call of move_AE() ?

"final" variables can not be changed or reset.

Sometimes it makes sense to make a new instance of the object that contains the final variable, but I don't know that this would be a help here.
