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) {

// TODO Auto-generated method stub

System.exit(0);

}

);

//注意：此处是匿名内部类

bl.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent e) {

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。

在线购物商品分类jsp，java代码怎么写，有父类子类的？

N种办法

1、mybatis 配置文件写SQL 解决

2、通过JAVA service 通过父类信息查询子类并封装

3、提供一个接口，前台二级联动方式，点第一个给后台传值0 ，查询父ID为0 的当点击第二个联动的时候把第一个信息的ID 给你传过去，如电子数码ID 为1 那就传1 后台还是根据父类查询，也就是父类ID 1 这样就查出所对应的子类信息了。
