Perhaps you missed this Announcement at the top of forum: http://www.daniweb.com/forums/announcement9-2.html

If you need help with it, you'll need to work up a first try at it or at least ask specific questions about what portion you do not understand.

It is not going to be that difficult. You just need to store stock entries in database and manage them , have a base class named product and derive all specific products in stock from the class product.

guys, this is what i've done so far however i'm not sure i'm going in the right direction.

public class Product {
	
	String name;
	double weight;
    int refNumber;
    int qty;
    double price;
    
    public Product(){
    	
    	name = "";
    	weight = 2.3;
    	refNumber = 001;
    	qty = 20;
    	price = 17.56;
    }
    
    
    public Product(String nameIn, int refNumberIn, double weightIn, int qtyIn, double priceIn)
    
    {
    	 name = nameIn;
    	 qty = qtyIn;
    	 weight = weightIn;
    	 refNumber = refNumberIn;
    	 price = priceIn;
    	 
    }
    
    public String getName()
    {
    	return name;
    }
    
    public double getWeight()
    {
    	return weight;
    }
    
    public int getRefNumber()
    {
    	return refNumber;
    }
    
    public int getQty()
    {
    	return qty;
    }
    
    public double getPrice()
    {
    	if(price<=0)
    	{
    		System.out.println("Invalid price!!");
    	} 
    	return price;
    	 
    }
    
    public String toString()
    {
        return "NAME: " + getName() + "\nREFNUMBER: " + getRefNumber() + "\nWeight: " + getWeight() +
                "\nQTY: " + getQty() + "\nPRICE: " + getPrice();

I'm not sure if the ArrayList class im using is the most appropriate for storing stock entries in the database.

[yellowflashboy]

By the way, the stock entry are to be stored in virtual database as i'm not actually required to physically design a database.
