 public static String getPDF() throws IOException {

        File file = new File("give complete path of file which must be read");
        FileInputStream stream = new FileInputStream(file);
        byte[] buffer = new byte[8192];
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int bytesRead;enter code here
        while ((bytesRead = stream.read(buffer)) != -1) {
            baos.write(buffer, 0, bytesRead);
        }
        System.out.println("it came back"+baos);
        byte[] buffer1= baos.toByteArray();
        String fileName = "give your filename with location";

        //stream.close();
        
        
         FileOutputStream outputStream =
                    new FileOutputStream(fileName);
         
         outputStream.write(buffer1);
        
         return fileName;
        
    }
