I am working on a shopping cart. I have list of books, each book has a link "Add to Cart", which adds books to a vector. When clicked on some other book it is also added to vector. I display all these books along with price and Author by enumerating through the vector.
Problem: I want to display the Grand total(price of book1 + price of book2) of books, how can i do that?
Part of code which displays elements of class shoppingcartElement is:
Enumeration en =vec.elements();
shoppingcartElement shopelement1 = (shoppingcartElement)en.nextElement();
//GrandTotal=shopelement1.total(previous instance)+(newinstance);
My shoppingcartElement class:
import java.lang.*;
import java.util.*;
public class shoppingcartElement extends Object{

public String bookname;
public double price ;
public int quantity;
public int sku;
public double total;
thanks for the help in advance.

GrandTotal = 0;
loop {
GrandTotal = GrandTotal+currentItem.price
