如何用Java編寫用戶注冊界面？

界面建議用可視化來做，美觀且便捷。下面這個是完全用代碼寫的，僅供參考。

import javax.swing.*;

import java.awt.event.*;

import java.awt.*;

import java.sql.*;

public class Register extends JFrame {

JLabel jl1 = new JLabel("用戶名");

JTextField jt1 = new JTextField();

JLabel jl2 = new JLabel("郵箱");

JTextField jt2 = new JTextField();

JLabel jl3 = new JLabel("密碼");

JPasswordField jpw1 = new JPasswordField();

JLabel jl4 = new JLabel("密碼確認(rèn)");

JPasswordField jpw2 = new JPasswordField();

JButton register = new JButton("注冊");

JButton clean = new JButton("清空");

public Register(){

setLayout(new GridLayout(5,2));

add(jl1);

add(jt1);

add(jl2);

add(jt2);

add(jl3);

add(jpw1);

add(jl4);

add(jpw2);

add(register);

add(clean);

String name = jt1.getText();

String email = jt2.getText();

String pw = jpw1.getText();

register.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent e){

try{

Class.forName("com.mysql.jdbc.Driver");

Connection con = DriverManager.getConnection("jdbc:mysql://localhost/db","root","");

Statement sta = con.createStatement();

sta.executeUpdate("INSERT INTO register VALUES(name,email,pw)");

JOptionPane.showMessageDialog(null,"注冊成功","提示",JOptionPane.INFORMATION_MESSAGE);

}

catch(Exception ex){

ex.getStackTrace();

}

}

});

clean.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent e){

jt1.setText("");

jt2.setText("");

jpw1.setText("");

jpw2.setText("");

}

});

}

public static void main(String[] args){

Register frame = new Register();

frame.setTitle("用戶注冊");

frame.setLocationRelativeTo(null);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setSize(400,400);

frame.setVisible(true);

}

}
