如何用Java編寫用戶註冊界面？

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”);

JPasswordField jpw2 = new JPasswordField();

JButton register = new JButton(“註冊”);

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,”註冊成功”,”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(“用戶註冊”);

frame.setLocationRelativeTo(null);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setSize(400,400);

frame.setVisible(true);

}

}

用java寫一個手機商城註冊界面代碼

這篇文章主要介紹了java通過JFrame做一個登錄系統的界面完整代碼示例，具有一定借鑒價值，需要的朋友可以參考下。

在java的JFrame內通過創建匿名對象的方式做登錄界面

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(“登錄”);

JButton bg=new JButton(“關閉”);

//構造無參構造器把主要的方法放在構造器里,然後在main方法裡面調

public LoginFrame(){

setBounds(25,25,250,250);

Container c = getContentPane();

c.setLayout(new GridLayout(4,2,10,10));

c.add(new JLabel(“用戶名”));

c.add(txtname);

c.add(new JLabel(“密碼”));

c.add(txtpass);

c.add(bl);

c.add(bg);

setDefaultCloseOperation(EXIT_ON_CLOSE);

setVisible(true);

//注意：此處是匿名內部類

bg.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent e) {

// TODO Auto-generated method stub

System.exit(0);

}

}

);

//注意：此處是匿名內部類

bl.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent e) {
