需要一JAVA写成的超市管理系统！主要就是超市货品的添加 ， 查询功能等！/**

public void setHuoWu(){
【java代码超市 java超市购物代码】HuoWu hw = new HuoWu();

String bianhao = sc.next();
java.util.Iterator it = list.iterator();
while(it.hasNext()){
if(bianhao.equals(((HuoWu)it.next()).bianhao)){
System.out.println("商品编号：" + ((HuoWu)it.next()).bianhao);
System.out.println("商品名称：" + ((HuoWu)it.next()).name);
System.out.println("商品价格：" + ((HuoWu)it.next()).jiage);
}
}
}
}
PS：程序可能还有点问题 ， 自己调试一下吧 。改天有空我再来更新 。
