Q2: 用java编一个超市销售界面的代码咋样写啊 ！急 谢谢各位啦
原先我写了个,你看看 可以直接运行,不过要先运行服务端,再运行客户端 至于就这简单,具体的代码你不懂再发消息我 *服务端* import java.awt.*;
Q3: Java编程，简单超市系统！！跪求啊
import java.util.Vector; class Supermarket{ Vector market = null; Supermarket(){ market = new Vector(); } public void append(Goods g){ market.addElement(g); } public void delete(Goods g){ market.removeElement(g); } public void query(Goods g){ for(int i = 0;imarket.size();i++){ if((market.elementAt(i)).equals(g) == true){ g.showMe(); } } } } class Goods{ private String name; private double price; private int num; public Goods(String name,double price,int num){ this.name=name; this.price = price; this.num = num; } public void sale(double buyprice){ if(num==0){ System.out.println("购买商品已售空"); return; } if(buypricethis.price){ System.out.println("余额不足"); }else{ num--; } } public void add(int quantity){ num+=quantity; } public void showMe(){ System.out.println("商品名称："+this.name+" 商品价格："+this.price+"$ "+"商品个数："+this.num); } } //很多地方给的不是很详细，只能这么凭理解写，测试main方法自己写。
Q4: 数据库如何用java写超市购物程序？
要使用Java编写超市购物程序，您需要使用Java数据库编程技术来连接到您的数据库并执行相关的数据库操作。在Java中，您可以使用JDBC（Java数据库连接）API来连接到数据库并执行SQL语句。例如，您可以使用JDBC API来执行以下操作：
创建数据库连接
执行增删改查（CRUD）操作
提交或回滚事务
执行存储过程和函数
查询数据库元数据
此外，您还可以使用Java的面向对象编程技术来封装数据库操作，以便更方便地在您的程序中使用。例如，您可以创建一个类来表示超市商品，并定义一些方法来执行商品的增删改查操作。这样，您就可以在程序中通过调用这些方法来简单地完成对数据库的操作，而不需要编写复杂的SQL语句。
