shoppingcartbean.java

JSF+Hibernate+Spring三层架构的一个例子

package pizzaria;
//购物车
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class ShoppingCartBean {
  ArrayList shoppingItems = new ArrayList();
  public ShoppingCartBean() {
  }
  public List getShoppingItems() {
    return shoppingItems;
  }
  
  public void setShoppingItems(List shoppingItems) {
    this.shoppingItems = new ArrayList(shoppingItems);
  }
  public void addShoppingItem(ShoppingItemBean item) {
    shoppingItems.add(item);
  }
  public void removeShoppingItems() {
    shoppingItems.clear();
  }
  public float getTotal() {
    float total = 0;
    Iterator iterator = shoppingItems.iterator();
    while (iterator.hasNext()) {
      ShoppingItemBean item = (ShoppingItemBean) iterator.next();
      total += item.getPrice() * item.getQuantity();
    }
    return total;
  }
}
