flipping memory cards if they are not matched...

i have made a memory card game and so far, I have done, clicking the JButton and showing the picture up. But my problem is to check the images if they are the same or not. If they are the same, I know what to do,. But if not, I don't know how to hide the image or flip the Jbutton so it would hide the image. I hope you can help me in this. Here is my code..,

Thank you

psst: don't forget the code tags! :)

I tried this another code but on the third click, I guess it didn't compare the pictures. Well, I go try and try. But I would really appreciate if you can give me some advice about this. Thank you.

I guess the hint didn't work, so we must try a different approach:

Hey, please use code tags!!!

I am sorry.. I always forget... I really am sorry.

Is this ok now?
i get some hint by playing with the code. I have a question. On the part of the code:

Code:

---

for (int i=0; i<pictureButton.length; i++){
                        if(pictureButton[i]==e.getSource()){
                                this.pictureButton[i].setIcon(pictureIcon[i]);

---

this is what i use to show the image when the button is clicked. I got an advice so use the counter so I have this one:

Code:

---

for (int i=0; i<pictureButton.length; i++){
                        if(pictureButton[i]==e.getSource()){
                                this.pictureButton[i].setIcon(pictureIcon[i]);
                                counter++;

                                if (counter==1){
                                        savepictureIcon[]=pictureButton[pictureIcon[i]];
                               
                                }
                                       
                        }
                }

---

But I realized what do I need that will contain the image of the first button clicked. the variable (savepictureIcon). so, i stopped there, thinking of how can i declare that kind of variable. The thing is, I would like to save the image to "savepictureIcon" then compare it with the picture on the second one. If they match, setEnabled(true) and if not, setEnabled(false). I keep on trying but it didn't work out. I don't receive any error but the buttons didn't change even if they are not of the same image.

I how you can help in this. Thank you.

I hope you can help me in this. Thank you.

Another question, is it possible to store the number of actionEvents? thank you.
