本文為大家分享了Java基於MySQL實現學生管理系統，供大家參考，具體內容如下
因為實驗室要交作業然後就做了一個學生管理系統，貼個代碼紀念一下，做的太急界面什麼的也比較差。
還有一些小細節沒有完善不過還是能實現主要的功能的。
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("學生管理系統") ; //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("查詢"); JButton button4 = new JButton("刪除"); JButton button5 = new JButton("瀏覽"); 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){ Add add = new Add(); } }); button2.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e){ Change change = new Change(); } }); button3.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e){ Ask ask = new Ask(); } }); button4.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e){ Delete delete = new Delete(); } }); button5.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e){ Look look = new Look(); } }); } }Add是添加
