        Scanner scan = new Scanner(System.in);
        int key=3;
        while (key-- != 0){

            System.out.print("顾客姓名：");
            String cust = scan.next(); //顾客姓名

            String prod = scan.next();
            if(mark.sell(prod) == 0)
                System.out.println(cust + "白跑一趟，什么都没有买到。");
            else
                System.out.println(cust + "买到了"+  prod + "，花费" + mark.getPrice(prod) + "元。");
        }

//SuperMark.java

        /* 获取商品的名字*/
