Question

public int open=0;
private JButton  opens[]=new JButton[1];

  for( i=0; i<buttons.length; i++){
            for (j=0; j<buttons[i].length;j++){ 
                n=i*buttons.length+buttons[i].length;
                buttons[i][j]=new JButton();

                panel.add(buttons[i][j]);

            JButton pressedButton = (JButton) e.getSource();
            opens[open]=(JButton) e.getSource();
            if((pressedButton.getIcon() == null)){
                pressedButton.setIcon(new ImageIcon(getClass().getResource("/images/2.jpg")));
                open=open++;
            } else {   
                //pressedButton.setIcon(null);

    }

I want to hold 2 clicked JButton and then close or stay open. How can i hold in array or something else?

My array holding is wrong?

With this code, i can open unlimited images and none of them is getting closed.

Answer 1

I am trying to hold 2 images in array, then it will close them if they are not same. It is a memory game. Only 2 images can be opened

• load Images to local variables as Icon/ImageIcons, to avoids any FileIO meaning code line pressedButton.setIcon(new ImageIcon(getClass().getResource("/images/2.jpg")));

• add this Icon/ImageIcons to JButton.setPressedIcon(myIcon),

• then there is useless code line to reset Icon back with pressedButton.setIcon(null);
