Writing the Constructor

Notice that MusicVideo inherits only from its parent 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

}

We need a constructor for MusicVideo. Use four parameters for title, length, artist and category. Initialize avail to true.
