这篇文章主要介绍Java基于MySQL实现学生管理系统的示例分析，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
本文为大家分享了Java基于MySQL实现学生管理系统，供大家参考，具体内容如下
因为实验室要交作业然后就做了一个学生管理系统，贴个代码纪念一下，做的太急界面什么的也比较差。
还有一些小细节没有完善不过还是能实现主要的功能的。
Window是主界面
package First;
import java.sql.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Window {
public static void main(String[] args){
JFrame jframe = new JFrame("学生管理系统") ; //window
Dimension d = new Dimension(400,300);
Point p = new Point (250,350);
jframe.setSize(d);
jframe.setLocation(p);
jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jframe.setVisible(true);
JButton button1 = new JButton("添加");
JButton button2 = new JButton("修改");
JButton button3 = new JButton("查询");
JButton button4 = new JButton("删除");
JButton button5 = new JButton("浏览");
FlowLayout flow = new FlowLayout(FlowLayout.LEFT,10,10);
JPanel panel = new JPanel(flow);
panel.add(button1);
panel.add(button2);
panel.add(button3);
panel.add(button4);
panel.add(button5);
jframe.add(panel);
button1.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){

}
});
button2.addActionListener(new ActionListener(){

}
});
button3.addActionListener(new ActionListener(){
