Playing sound files:

• The classes “Media” and “MediaPlayer” are used to play audio files.
• The audio file is been loaded into memory by “Media” class.
• The methods for playing audio files are been provided by “MediaPlayer” class.
• The steps involved in process of playing an audio file includes:
  • The audio file is been loaded into memory.
    • An instance of “Media” class is been created.
    • The constructor is been passed with URL that specifies name of file and its location.
  • The audio file is been played.
    • An instance of “MediaPlayer” class is been created.
    • The constructor is been passed with media object as an argument.
    • The methods that help to play audio file includes:
      • setAutoPlay(value):
        • If value “true” is been passed as argument, then audio file is immediately played.
        • It starts playing from beginning of file.
      • play():
        • It starts playing sound file.
        • Normally, it starts playing audio file from beginning.
        • If sound file is been paused currently, the method resumes from point it was paused.
      • pause():
        • It pauses the sound file.
        • The “play” method causes audio file to resume playing at point where it was paused.
      • stop():
        • It stops audio file’s playback.
        • Now, if “play” method is used, audio file starts playing from beginning...
