用java怎么实现QQ登录界面？

用java做QQ登录界面的写法如下：

package ch10;

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

1、//定义该类继承自JFrame，实现ActionListener接口

public class LoginTest extends JFrame implements ActionListener

{

2、//创建JPanel对象

private JPanel jp=new JPanel();

3、//创建3个标并加入数组

JLabel name = new JLabel("请输入用户名");

JLabel password = new JLabel("请输入密码");

JLabel show = new JLabel("");

private JLabel[] jl={name,password,show};

4、//创建登陆和重置按扭并加入数组

JButton login = new JButton("登陆");

JButton reset = new JButton("重置");

private JButton[] jb={login,reset};

5、//创建文本框以及密码框

private JTextField jName=new JTextField();

private JPasswordField jPassword =new JPasswordField();

public LoginTest()

{

6、//设置布局管理器为空布局，这里自己摆放按钮、标签和文本框

jp.setLayout(null);

for(int i=0;i2;i++)

{

7、//设置标签和按扭的位置与大小

jl[i].setBounds(30,20+40*i,180,20);

jb[i].setBounds(30+110*i,100,80,20);

8、//添加标签和按扭到JPanel容器中

jp.add(jl[i]);

jp.add(jb[i]);

//为2个按钮注册动作事件监听器

jb[i].addActionListener(this);

}

9、//设置文本框的位置和大小，注意满足美观并足够用户名的长度

jName.setBounds(130,15,100,20);

10、//添加文本框到JPanel容器中

jp.add(jName);

11、//为文本框注册动作事件监听器

jName.addActionListener(this);

12、//设置密码框的位置和大小，注意满足美观和足够密码的长度

jPassword.setBounds(130,60,100,20);

13、//添加密码框到JPanel容器中

jp.add(jPassword);

14、//设置密码框中的回显字符，这里设置美元符号

jPassword.setEchoChar('$');

15、//为密码框注册动作事件监听器

jPassword.addActionListener(this);

16、//设置用于显示登陆状态的标签大小位置，并将其添加进JPanel容器

jl[2].setBounds(10,180,270,20);

jp.add(jl[2]);

17、//添加JPanel容器到窗体中

this.add(jp);

18、//设置窗体的标题、位置、大小、可见性及关闭动作

this.setTitle("登陆窗口");

this.setBounds(200,200,270,250);

this.setVisible(true);

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

19、//实现动作监听器接口中的方法actionPerformed

public void actionPerformed(ActionEvent e)

{

20、//如果事件源为文本框

if(e.getSource()==jName)

{

21、//切换输入焦点到密码框

jPassword.requestFocus();

}

22、//如果事件源为重置按扭

else if(e.getSource()==jb[1])

{

23、//清空姓名文本框、密码框和show标签中的所有信息

jl[2].setText("");

jName.setText("");

jPassword.setText("");

24、//让输入焦点回到文本框

jName.requestFocus();

}

25、//如果事件源为登陆按钮，则判断登录名和密码是否正确

else

{

26、//判断用户名和密码是否匹配

if(jName.getText().equals("lixiangguo")

String.valueOf(jPassword.getPassword()).equals("19801001"))

{

27、jl[2].setText("登陆成功，欢迎您的到来！");

}

else

{

28、jl[2].setText("对不起，您的用户名或密码错误！");

}

}

}

public static void main(String[] args)

{

29、//创建LoginTest窗体对象

new LoginTest();

}

}
