I figured out my last problem, but have I another one.

Question

This one is difficult for me because it compiles and runs so I have trouble to pinpoint the problem. When it runs every is left blank. I will put an example under the code.
import java.util.Scanner;
import java.text.*;
public class DVDInventory33
public static void main(String[] args)
       Scanner input = new Scanner( System.in );
       int j;

      // create DVD object
      inventory [ 0 ] = new DVD_Genre( "Rocky", "Action/Drama", 01, 5, 9.95 );
      inventory [ 1 ] = new DVD_Genre( "RockyII", "Action/Drama", 02, 3, 14.95 );
      inventory [ 2 ] = new DVD_Genre( "Matrix", "Action/Sci-Fi", 03, 3, 14.95 );
      inventory [ 3 ] = new DVD_Genre( "MatrixII", "Action/Sci-Fi", 04, 1, 19.95 );
      inventory [ 4 ] = new DVD_Genre( "Bambi", "Family", 05, 5, 12.95 );
      // Print out a screen title

DVD Title:

Value of DVD's: $0.00
The entire inventory value is : $0.0
The restock fee is : $0.0
I am trying to find where the problem lays.

Answer 1

And the DVD/DVD_Genre parent/child looks fishy.
A DVD_Genre is a special kind of DVD? It's a kind of DVD that, unlike a regular DVD, has a genre and a restock fee? What's the connection beetween genre and restock fee? Regular, non-genre DVDs don't have restock fees? Why would one create a DVD with no genre?
