  • I guess you could make it a string and then do getBytes on it? I've personally had this same issue some days ago and I juset went with Apache Commions IO solution. val byteArray = org.apache.commons.io.IOUtils.toByteArray(inputFiles) , why do you not wanna use that?

  • This also might work? val bis = new BufferedInputStream(new FileInputStream(fileName)) val bArray = Stream.continually(bis.read).takeWhile(-1 !=).map(_.toByte).toArray taken from: stackoverflow.com/questions/7598135/… Commented Jul 6, 2020 at 15:36
