A good answer might be:

Jaws, 120 min. available: true

Using Inheritance

The VideoTape class has basic information in it, and would be OK for documentaries and instructional tapes. But movies need more information. Let us make a class that is similar to VideoTape, but has the name of the director and a rating. 

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 Movie extends VideoTape
{
  String  director;     // name of the director
  String  rating;       // G, PG, R, or X

  // constructor
  public Movie( String ttl, int lngth, String dir, String rtng )
  {
    super( ttl, lngth );                 // use the super class' constuctor
    director = dir;  rating = rtng;      // initialize what's new to Movie
  }

}

The class Movie is a subclass of VideoTape. An object of type Movie has the following members in it:

member  
title inherited from VideoTape
length inherited from VideoTape
avail inherited from VideoTape
show() inherited from VideoTape
directordefined in Movie
rating defined in Movie

Both classes are defined: the VideoTape class can be used to construct objects of that type, and now the Movie class can be used to construct objects of the Movie type.
