Store an Array of Classes e.g. Order / Line Items example

Question

Hello, I am having trouble storing an array of classes, they all end up having the same value.
Consider the following simple class definition:
Class Order
private LineItem[] lineItems;
Class LineItem(amount, price)
private int amount;
private float price;
Consider the following pseudo code as part of the constructor of class order (to fill the array with a bunch of LineItems):
for x = 1 to 10
lineItems[x] = new LineItem(amount, price);
however all lineItems[x] have the same LineItem
any ideas?

Answer 1

i posted the design since its a bit more complicated then my summarized version, but at any rate i will post the full solution for those who want to view either or...
basically this takes an XML field and creates an object Order which has some attributes plus an array of Line Item objects.
