1、//定義該類繼承自JFrame，實現(xiàn)ActionListener接口

public class LoginTest extends JFrame implements ActionListener

{

2、//創(chuàng)建JPanel對象

private JPanel jp=new JPanel();

3、//創(chuàng)建3個標(biāo)并加入數(shù)組

JLabel name = new JLabel("請輸入用戶名");

JLabel password = new JLabel("請輸入密碼");

JLabel show = new JLabel("");

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

4、//創(chuàng)建登陸和重置按扭并加入數(shù)組

JButton login = new JButton("登陸");

JButton reset = new JButton("重置");

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

5、//創(chuàng)建文本框以及密碼框

private JTextField jName=new JTextField();

private JPasswordField jPassword =new JPasswordField();

public LoginTest()

{

6、//設(shè)置布局管理器為空布局，這里自己擺放按鈕、標(biāo)簽和文本框

jp.setLayout(null);

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

{

7、//設(shè)置標(biāo)簽和按扭的位置與大小

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

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

8、//添加標(biāo)簽和按扭到JPanel容器中

jp.add(jl[i]);

jp.add(jb[i]);

//為2個按鈕注冊動作事件監(jiān)聽器

jb[i].addActionListener(this);

}

9、//設(shè)置文本框的位置和大小，注意滿足美觀并足夠用戶名的長度

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

10、//添加文本框到JPanel容器中

jp.add(jName);

11、//為文本框注冊動作事件監(jiān)聽器

jName.addActionListener(this);

12、//設(shè)置密碼框的位置和大小，注意滿足美觀和足夠密碼的長度

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

13、//添加密碼框到JPanel容器中

jp.add(jPassword);

14、//設(shè)置密碼框中的回顯字符，這里設(shè)置美元符號

jPassword.setEchoChar('$');

15、//為密碼框注冊動作事件監(jiān)聽器

jPassword.addActionListener(this);

16、//設(shè)置用于顯示登陸狀態(tài)的標(biāo)簽大小位置，并將其添加進JPanel容器

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

jp.add(jl[2]);

17、//添加JPanel容器到窗體中

this.add(jp);

18、//設(shè)置窗體的標(biāo)題、位置、大小、可見性及關(guān)閉動作

this.setTitle("登陸窗口");

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

this.setVisible(true);

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

19、//實現(xiàn)動作監(jiān)聽器接口中的方法actionPerformed

public void actionPerformed(ActionEvent e)

{

20、//如果事件源為文本框

if(e.getSource()==jName)

{

21、//切換輸入焦點到密碼框

jPassword.requestFocus();

}

22、//如果事件源為重置按扭

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

{

23、//清空姓名文本框、密碼框和show標(biāo)簽中的所有信息

jl[2].setText("");

jName.setText("");

jPassword.setText("");

24、//讓輸入焦點回到文本框

jName.requestFocus();

}

25、//如果事件源為登陸按鈕，則判斷登錄名和密碼是否正確

else

{

26、//判斷用戶名和密碼是否匹配

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

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

{

27、jl[2].setText("登陸成功，歡迎您的到來！");

}

else

{

28、jl[2].setText("對不起，您的用戶名或密碼錯誤！");

}

}

}

public static void main(String[] args)

{

29、//創(chuàng)建LoginTest窗體對象

new LoginTest();

}

}

怎么用java打開qq

java實現(xiàn)簡單QQ登陸界面：

1.生成界面的java代碼

package?QQ2014;

//創(chuàng)建聊天記錄，輸入域

JTextArea?area_input=new?JTextArea(10,30);

JTextArea?area_record=new?JTextArea(5,30);

//創(chuàng)建流式分布對象

FlowLayout?layout=new?FlowLayout(FlowLayout.CENTER,0,10);

復(fù)制代碼

2.java?main方法調(diào)用

package?QQ2014;

public?class?Test?{

public?static?void?main(String[]?args){

QQ2014?qq=new?QQ2014();

qq.showLoginFrame();

}

}
