What instance variables are part of the class MusicVideo?

A good answer might be:

MusicVideo inherits title, length, and avail from its superclass and adds artist and category.

Writing the Constructor

Notice that MusicVideo inherits only from its superclass VideoTape. It does not inherit anything from its sibling class Movie. Here is the definition so far: 

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 );
  }
  
}

class MusicVideo extends VideoTape
{
  String artist;
  String category;

  // The constructor will go here

  // The show() method will go here

}

A constructor is needed for MusicVideo. The constructor will use four parameters to initialize title, length, artist and category. Initialize avail to true without using a parameter.
