try {
                String a = textField_1.getText(); //my image path
                InputStream barCodeInputStream = new FileInputStream(""+a);
                BufferedImage barCodeBufferedImage = ImageIO.read(barCodeInputStream);

                LuminanceSource source = new BufferedImageLuminanceSource(barCodeBufferedImage);
                BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));
                MultiFormatReader reader = new MultiFormatReader();
                com.google.zxing.Result result = reader.decode(bitmap);

                System.out.println("Barcode text is " + result.getText());
                textField.setText(""+result.getText());
            } catch (Exception e) {
                // TODO: handle exception
                JOptionPane.showMessageDialog(null, "This image does not contain barcode", "Warning", JOptionPane.WARNING_MESSAGE);
                e.printStackTrace();
            }
