Q3: 用java写一个手机商城注册界面代码
这篇文章主要介绍了java通过JFrame做一个登录系统的界面完整代码示例，具有一定借鉴价值，需要的朋友可以参考下。
在java的JFrame内通过创建匿名对象的方式做登录界面
package com.sxt;
import java.awt.Container;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;
public class LoginFrame extends JFrame{
JTextField txtname=new JTextField();
JPasswordField txtpass=new JPasswordField();
JButton bl=new JButton("登录");
JButton bg=new JButton("关闭");
//构造无参构造器把主要的方法放在构造器里,然后在main方法里面调
public LoginFrame(){
setBounds(25,25,250,250);
Container c = getContentPane();
c.setLayout(new GridLayout(4,2,10,10));
c.add(new JLabel("用户名"));
c.add(txtname);
c.add(new JLabel("密码"));
c.add(txtpass);
c.add(bl);
c.add(bg);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setVisible(true);
//注意：此处是匿名内部类
bg.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {

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。
