A good answer might be:

The finished class is given below.

Complete MusicVideo Class

The subclass (MusicVideo) can use super anywhere within its own show() method. It is used in the first statement here because that is where it makes the most sense. 

class VideoTape
{
  // stuff ommitted here
  public void show()
  {
    System.out.println( title + ", " + length + " min. available:" + avail );
  }
  
}

class MusicVideo extends VideoTape
{
  String artist;
  String category;
 
  // constructor
  public MusicVideo ( String ttl, int len, String art, String cat )
  {
    super( ttl, len );
    artist   = art;
    category = cat;
  }
  
  public void show()
  {
    super.show();
    System.out.println( "artist:" + artist + " style: " + category );
  }
}
