[Thought question:] Can you use one of your own classes (not a predefined class like Applet) as a parent class?

A good answer might be:

Yes. Programming in Java consists mostly of creating class hierarchies and instantiating objects from them.

Tape Store Example

Here is a program that uses a class VideoTape to represent tapes available at a video tape rental store. Inheritance is not used in this program (so far). 

class VideoTape
{
  String  title;    // name of the item
  int     length;   // number of minutes
  boolean avail;    // is the tape in the store?

  public VideoTape( String ttl, int lngth )
  {
    title = ttl; length = lngth; avail = true; 
  }

  public void show()
  {
    System.out.println( title + ", " + length + " min. available:" + avail );
  }
  
}

class TapeStore
{
  public static void main ( String args[] )
  {
    VideoTape item1 = new VideoTape("Jaws", 120 );

    item1.show();
  }
}

You can run this program using the "copy-paste-and-run" method.
