Lab for All, By Mukhtiar Zamin

We are going to create an audio player that should be able to play audios in mp3, mp4 and vlc formats. 

 Click on www.tutorialspoint.com to access its starting code.  

Watch the following video to understand how we develop it with Adapter pattern.

Lab Tasks
  1. Add a support of one another format in the default AudioPlayer
  2. Add two more classes each one support another format of the audio that implements AdvancedMediaPlayer and then utilize them from the main method.
  3. Simplify the AdvancedMediaPlayer interface such that dummy methods are not required to be implemented in the concrete player class. For example PlayVlc method in Mp4Player class is with a dummy definition and not in use.
