Question

 public BufferedImage readImage(String fileLocation) {
        BufferedImage img = null;

        File file = new File("D:\\logo.jpg");
            img = ImageIO.read(file);
}

throwing error can;t read the file

Answer 1

The code should be like as follows,

BufferedImage img = null;
try {
     img = ImageIO.read(new File("D:\\logo.jpg"));
} catch (IOException e) {
      System.out.println("Exception is --- "+ e.getMessage());
      e.printStackTrace();
}

Then you can trace actual cause of the problem as we are printing message and stack trace if exception occurs.
