So far the video rental application has two classes: 
VideoTape and Movie.
Say that you wanted to create a new class, 
MusicVideo that will be like
VideoTape but will have two new instance variables:
artist 
(the name of the performer)
and category 
("R&B", "Pop", "Classical", "Other" ).
Both of these will be Strings.
The MusicVideo class will need its own 
constructor and its own show() method.
Here is the parent class:
class VideoTape
{
  String  title;    // name of the item
  int     length;   // number of minutes
  boolean avail;    // is the tape in the store?
  // constructor
  public VideoTape( String ttl, int lngth )
  {
    title = ttl; length = lngth; avail = true; 
  }
  public void show()
  {
    System.out.println( title + ", " + length + " min. available:" + avail );
  }
  
}
The new class looks like this:
class ______________ extends _________________ { String ______________; // the artist String ______________; // the music category // constructor will go here (skip for now) // show method will go here (skip for now) }
