java 如何模仿QQ聊天框那样可以显示文字与图片啊？

1、swing的界面可以直接用netbeans画出来嘛。

2、可以把输出的聊天内容都放在一个StringBuffer里，每打出一句话，就把这句话追加在StringBuffer，然后把StringBuffer里的内容输出到Textarea中。

3、好友列表可以用JList

写一个java程序，类似QQ聊天，但功能简单得多，要求己方为服务器端，提供端口让好友来连接，连接上

本来就要先开服务器啊；

首先，开启服务器；

客户端连接服务器，一连上服务器，说明客户上线上；

通过客户端查看好友是否上线，如果上线，可以直接进行聊天，如果没上线，也可以给好友留言；

两个客户端进行聊天的原理：客户（A与B）：A要发消息给B，首先，要把A的账号（发送者），A要发送的内容和B的账号（接收者），发送时间打包通过线程发给服务器；

服务器进行解包，查看B的账号是否上线，如果上线，再把这个包发给B，B进行解包，显示在界面上；B要发给A也是同理。。

你说的两个客户端直接聊天，其实相当于服务器与客户端的聊天而已，这样的聊天程序是不完整的。

希望能帮到你。

求一个用java编写的套接字实现类似于QQ对话的程序，急用

有两个类，服务器和客户端、

服务器类代码：

package chat;

import java.io.*;

import java.net.*;

import java.util.*;

/*服务器类*/

public class Server {

public ListSocket socketList = new ArrayListSocket();//存放所有连接的客户端的集合

public ServerSocket server;//服务器

public int portNum;//端口号

public Server(int portNum){

this.portNum = portNum;

}

public void innit(){

try {

server = new ServerSocket(portNum);

System.out.println("服务器开启成功！");

int socketNum = 0;

while(true){

Socket socket = server.accept();//被动等待客户端的连接

socketNum++;

System.out.println("第"+socketNum+"个客户端连接成功！！");

socketList.add(socket);//连接的客户端存放到集合里面

new RWThread(socket).start();

}

} catch (IOException e) {

e.printStackTrace();

}

}

class RWThread extends Thread{//接收和发送消息的线程

public Socket socket;

public RWThread(Socket socket){

this.socket = socket;

}

public void run() {

super.run();

try {

BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));

while(true){

String message = br.readLine();

System.out.println(message);//接收客户端发来的消息

for(int i=0;isocketList.size();i++){//发送给所有连接的客户端

PrintWriter pw = new PrintWriter(new OutputStreamWriter(socketList.get(i).getOutputStream()));

pw.println(message);

pw.flush();

}

}

} catch (IOException e) {

e.printStackTrace();

}

}

}

public static void main(String[] args) {

int portNum = 8888;//创建服务器的端口号

Server server = new Server(portNum);

server.innit();

}

}

客户端类：

package chat;

import java.io.*;

import java.net.*;

import java.util.*;

/*客户端类*/

public class Client {

public Socket socket;

public Client(){

Scanner sca = new Scanner(System.in);

try {

socket = new Socket("127.0.0.1",8888);//创建客户端

new ReadThread(socket).start();//开启读取从服务器端发来的信息

while(true){

PrintWriter pw = new PrintWriter(new OutputStreamWriter(socket.getOutputStream()));

String message = sca.nextLine();

pw.println(message);//向服务器发送信息

pw.flush();

}

} catch (UnknownHostException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

System.out.println("错误：服务器未开启！！！");

}

}

class ReadThread extends Thread{//读取服务器发来信息的线程

public Socket socket;

public ReadThread(Socket socket){

this.socket = socket;

}

public void run() {

super.run();

try {

BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));

while(true){

String message = br.readLine();

System.out.println(message);//输出信息

}

} catch (IOException e) {

e.printStackTrace();

}

}

}

public static void main(String[] args) {

Client client = new Client();

}

}

现打开服务器类，然后可以打开多个客户端进行聊天

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();

}

}
