为什么我这里只会输出第一个添加进去的商品的价格
public static void main(String[] args) {
//先创建两个商品对象
Items i1 = new Items(1,"沃特篮球鞋","温州",200,500,"001.jpg");
Items i2 = new Items(2,"李宁运动鞋","广州",300,500,"002.jpg");
Cart cart = new Cart();
cart.addGoodsInCart(i1, 1);
cart.addGoodsInCart(i2, 3);
System.out.println("购物车的总结额："+cart.getTotalPrice());
}
}
