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