Обновление изображений меток значков с сохранением значков меток, которые не были изменены

/ 10 ноября 2019

В моем jframe 6 ярлыков с иконками изображений, рядом с другими текстовыми полями и датой. У меня проблема с кнопкой UPDATE, поскольку я не могу сохранить значок метки содержимого при обновлении чего-либо еще. Поэтому каждый раз, когда я запускаю запрос, он устанавливает все мои значки меток на Null.

Мне нужно только знать, как получить содержимое моей иконки jlabel, как я делаю это с другими текстовыми полями, чтобы я мог сохранитьэто когда я запускаю мой запрос на обновление, потому что, конечно, байтовые массивы BeforePhoto, BeforePhotoRight, BeforePhotoLeft, BeforePhotoBack все будут нулевыми в момент, когда я выполняю свой запрос на обновление.

ЭТО МОЯ функция JFileChooser: 

private void cmd_insertBeforeActionPerformed(java.awt.event.ActionEvent evt) {                                                 
    JFileChooser chooser = new JFileChooser();
    chooser.showOpenDialog(null);
    File f = chooser.getSelectedFile();
    filename = f.getAbsolutePath();
    try {
        File image = new File(filename);
        FileInputStream fis = new FileInputStream(image);
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        byte[] buf = new byte[1024];
        for(int readNum; (readNum=fis.read(buf))!=-1;){
        bos.write(buf,0,readNum);
        }
    BeforePhoto = bos.toByteArray();
    ImageIcon imageIcon = new ImageIcon(new ImageIcon(filename).getImage().getScaledInstance(label_before.getWidth(), label_before.getHeight(),Image.SCALE_SMOOTH));
    label_before.setIcon(imageIcon);
    } catch (Exception e) {
        JOptionPane.showMessageDialog(null, e);
       e.printStackTrace();

    } finally {
        try {
            rs.close();
            pst.close();
        } catch(Exception e) {

        }
    }
