What is the difference between these objects?

Question

Please, can any one tell me the diffrence between the two objects below, in terms of when to use one or the other.
This code is from a structs application. The objects are created from same form bean.
package net.hus.orderbook.action;
import net.hus.orderbook.form. TakeOrderForm ;
public class TakeOrderAction extends DispatchAction {
// showorder action method.
public ActionForward showOrderForm(ActionMapping mapping, ActionForm wForm, HttpServletRequest request, HttpServletResponse response) {
TakeOrderForm form = new TakeOrderForm();  // object 1
   TakeOrderForm oldForm = (TakeOrderForm)wForm;  // object 2
}Thanks

Hey CyprayDeJava,
I am not sure of all the intricacies but
TakeOrderForm form = new TakeOrderForm();
creates the form using the constructor of the object TakeOrderForm.
and
TakeOrderForm oldForm = (TakeOrderForm)wForm;
creates the oldForm by casting the wForm, which is of type ActionForm, to an TakeOrderForm.
