Object Array ? Do you Worth it

[ashish]

Is anyone who can solve this problem qwith object array. Those classes related
with the programs are, Video Class, Game Class; theese are extended classes
of Item class. And Library class, Member Class, There is also a class called
interface class but I am not sending it in here. All the other class except
Library class seem to work . Can any one sort the library class as well .
I expecting the reply on the DevGuru page and on my e mail add as well. My
add is ashisharyal@hotmail.com


public abstract class Item
{
public String itemTitle;
public int itemID, memberID;
private static int nextID = 1; // static class variable in Item
public boolean addItemOK;

public Item()//default constructor
{

public Item(String title )//specific constructor

What 'doesn't work'? I scanned the code and saw multiple issues/problems.
