2. in to uri.tostring there should be a error of incompatible of file into string and there is no option of mediaview. i think u understand what can i write…..plz sugeest a solution

   1. Hi, It could be because you haven’t downloaded any media or the directory path isn’t pointing to the place where the media is being kept? Try checking these things and letting me know if the problem still persists. Thank you.

3. thanks, 🙂

   Sir, this is my whole code. But it is not working. It keep on throwing Exception. Please correct my mistakes and let me know ASAP. Thank You.

7. Thanks for this man, a real eye opener. Though it will be a milestone to completely transition from swing to JFX

8. Great Job! Did you notice the bug in the oracle code for formatTime? It doesn’t work right if the movie is over an hour long.

   Bugs. Bugs. Bugs.

   Bugs. Bugs.Bugs.

   Wonderful Bugs. Wonderful Bugs! Yes I have gone stark raving mad.

9. Here is a fix by the way……..

   private static String formatTime(Duration elapsed, Duration duration) {

   if (elapsed.greaterThan(Duration.ZERO) && duration.greaterThan(Duration.ZERO)) {
   long duration_ms = (long) Math.floor(duration.toMillis());
   long elapsed_ms = (long) Math.floor(elapsed.toMillis());

   return String.format(“%s%s of %s”,”Duration “, milliToHourFormat(elapsed_ms), milliToHourFormat(duration_ms));
   } else {
   return “”;
   }
   }

   private static String milliToHourFormat(long milliseconds) {
   int seconds = (int) (milliseconds / 1000) % 60;
   int minutes = (int) ((milliseconds / (1000 * 60)) % 60);
   int hours = (int) ((milliseconds / (1000 * 60 * 60)) % 24);
   StringBuffer sb = new StringBuffer();
   if (hours > 0) {
   sb.append(hours);
   sb.append(“:”);
   }
   if (minutes < 10) {
   sb.append("0");
   sb.append(minutes);
   sb.append(":");
   } else {
   sb.append(minutes);
   sb.append(":");
   }
   if (seconds < 10) {
   sb.append("0");
   sb.append(seconds);
   } else {
   sb.append(seconds);
   }
   return sb.toString();
   }

   Enjoy!

10. The above comment should be sung to the tune of “Wonderful Spam” by Monty Python…
