Need help bad!!

[ddmeightball]

OK, i figured out what i was doing wrong. I didnt have an it() method. Now it works. Thanks

public Iterator it()
    {
        return products.iterator();
    }

here is the finished code for both my methods.

first Product.java

/**
 * Title:        Assign 2
 * @author       Matthew Davis
 * School		 SECC
 * Class		 Advanced Java
 */
public class Product{
	private String code;
	private String name;
	private double price;

	public Product(){
	}

	public Product(String code, String name, double price)
		{
			this.code = code;
			this.name = name;
			this.price = price;
		}

	public void setCode(String c)
		{
			code = c;
		}
		
	public String getCode()
		{ 
			return code;
		}

	public void setName(String n)
		{
			name = n;
		}
		
	public String getName()
		{ 
			return name;
		}

	public void setPrice(double p)
		{
			price = p;
		}
		
	public double getPrice()
		{ 
			return price; 
		}
		
	public String toString()
		{
			return code + "\t" + name + "\t" + price + "\t";
			//return code + " " + name + " " + price;
		}


}

and now my productList.java

/**
 * Title:        Assign 2
 * @author       Matthew Davis
 * School		 SECC
 * Class		 Advanced Java
 */

import java.util.*;

public class ProductList extends Product{
	ArrayList products = new ArrayList();

	public ProductList() {

	}

	public void add(Product p)
		{//add a product to the list
			products.add(p);
			
		/*String key = ((Product)p).getCode();
			if(find(key) == null)
				{
					products.add(p);
				}*/
		}

	public void add(String id, String name, double price)
		{//create a Product and add it to the list
			for(int i = 0 ; i<products.size(); i++)
				{
					Product prod1 = new Product(id,name,price);
					products.add(prod1);
				}
		}

	public int size()
		{//return how many are in the list
			return products.size();
		}
	
	public Object get(int index)
		{//return the Product at position index
			return products.get(index);
		}
		
	public void remove(int index)
		{//remove the Product at position index
			products.remove(index);
		}
	
	public Object find(String find)
		{//return a Product based on the ID#
			Iterator it = products.iterator();
			
			while(it.hasNext())
				{				
					Product q = (Product)it.next();
					if (q.getCode().equals(find))
					{
						return q;
					}
				}
			return null;
		}
		
public Iterator it()
    {
        return products.iterator();
    }

		
	public static void main(String[] args) 
		{
			ProductList pr = new ProductList();
            
            Product prod1 = new Product("5248","trumpet" , 50);
            Product prod2 = new Product("5420","Saxaphone" , 100);
            
            pr.add(prod1);
            pr.add(prod2);
            
            Iterator it = pr.it();
            
            while (it.hasNext())            
            {
                Product p = (Product)it.next();
                System.out.println(p.toString());
            }
   
			
		}
	}
