多进程多线程--图形界面聊天室代码

多进程多线程--图形界面聊天室是一种基于socket(TCP)通信的应用程序，它可以实现多个用户之间的实时聊天。在该应用程序中，使用了多进程和多线程技术，其中一个进程负责终端操作，另一个进程负责图形化界面操作，两个进程之间通过管道进行通信。同时，为了提高程序的并发性能，使用了多线程技术，每个客户端连接到服务器时，服务器会为其创建一个新的线程，用于处理该客户端的请求。这样，多个客户端之间的聊天就可以同时进行，而不会相互影响。

好的，我会尽力回答您的问题。 首先需要了解一下Java的Socket通信，Socket是一种网络通信协议，它是一种应用层协议，用于实现进程间的通信和网络间的通信。 在Java中，可以通过java.net包中的Socket类和ServerSocket类来实现Socket通信。 为了实现多人多线程聊天室，我们需要采用ServerSocket类来实现服务器端，客户端可以采用Socket类来实现。 以下是大致的代码实现： 服务端： ```java import java.io.*; import java.net.*; import java.util.*; public class Server { private ServerSocket server; private ArrayList<Socket> clients; public Server(int port) { clients = new ArrayList<>(); try { server = new ServerSocket(port); System.out.println("Server started."); } catch (IOException e) { System.out.println("Failed to start server."); e.printStackTrace(); System.exit(-1); } } public void start() { while (true) { try { Socket client = server.accept(); clients.add(client); ClientHandler handler = new ClientHandler(client, clients); new Thread(handler).start(); System.out.println("New client connected."); } catch (IOException e) { System.out.println("Client connection error."); e.printStackTrace(); } } } public static void main(String[] args) { Server server = new Server(8888); server.start(); } } class ClientHandler implements Runnable { private Socket client; private ArrayList<Socket> clients; private BufferedReader in; private PrintWriter out; public ClientHandler(Socket client, ArrayList<Socket> clients) { this.client = client; this.clients = clients; try { in = new BufferedReader(new InputStreamReader(client.getInputStream())); out = new PrintWriter(client.getOutputStream(), true); } catch (IOException e) { System.out.println("Failed to create input/output stream."); e.printStackTrace(); } } @Override public void run() { try { String name = in.readLine(); System.out.println("New client " + name + " connected."); out.println("Welcome " + name + " to the chat room."); for (Socket c : clients) { if (!c.equals(client)) { PrintWriter p = new PrintWriter(c.getOutputStream(), true); p.println(name + " has joined the chat room."); } } String line; while ((line = in.readLine()) != null) { System.out.println(name + ": " + line); for (Socket c : clients) { if (!c.equals(client)) { PrintWriter p = new PrintWriter(c.getOutputStream(), true); p.println(name + ": " + line); } } } clients.remove(client); for (Socket c : clients) { PrintWriter p = new PrintWriter(c.getOutputStream(), true); p.println(name + " has left the chat room."); } client.close(); System.out.println("Client " + name + " disconnected."); } catch (IOException e) { System.out.println("Failed to communicate with the client."); e.printStackTrace(); } } } ``` 客户端： ```java import javax.swing.*; import java.awt.*; import java.awt.event.*; import java.io.*; import java.net.*; import java.util.*; public class Client extends JFrame { private Socket socket; private BufferedReader in; private PrintWriter out; private JTextArea messageArea; private JTextField messageField; private JButton sendButton; private JButton joinButton; private JButton exitButton; private boolean connected; public Client() { super("Chat Room"); connected = false; messageArea = new JTextArea(); messageArea.setEditable(false); JScrollPane scrollPane = new JScrollPane(messageArea); messageField = new JTextField(); sendButton = new JButton("Send"); sendButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { sendMessage(); } }); joinButton = new JButton("Join"); joinButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { joinChatRoom(); } }); exitButton = new JButton("Exit"); exitButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { exitChatRoom(); } }); JPanel buttonPanel = new JPanel(); buttonPanel.setLayout(new GridLayout(1, 3)); buttonPanel.add(joinButton); buttonPanel.add(exitButton); buttonPanel.add(sendButton); JPanel messagePanel = new JPanel(); messagePanel.setLayout(new BorderLayout()); messagePanel.add(scrollPane, BorderLayout.CENTER); messagePanel.add(messageField, BorderLayout.SOUTH); messagePanel.add(buttonPanel, BorderLayout.NORTH); setContentPane(messagePanel); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(500, 300); setVisible(true); } private void sendMessage() { if (connected) { String message = messageField.getText(); if (!message.equals("")) { out.println(message); messageField.setText(""); } } } private void joinChatRoom() { if (!connected) { String name = JOptionPane.showInputDialog(this, "Please enter your name:"); if (name != null && !name.equals("")) { try { socket = new Socket("localhost", 8888); in = new BufferedReader(new InputStreamReader(socket.getInputStream())); out = new PrintWriter(socket.getOutputStream(), true); out.println(name); messageArea.append(in.readLine() + "\n"); connected = true; joinButton.setEnabled(false); exitButton.setEnabled(true); sendButton.setEnabled(true); Thread listener = new Thread(new MessageListener()); listener.start(); } catch (IOException e) { JOptionPane.showMessageDialog(this, "Failed to connect to the server."); e.printStackTrace(); } } } } private void exitChatRoom() { if (connected) { out.println("exit"); connected = false; joinButton.setEnabled(true); exitButton.setEnabled(false); sendButton.setEnabled(false); try { socket.close(); } catch (IOException e) { JOptionPane.showMessageDialog(this, "Failed to close the socket."); e.printStackTrace(); } } } class MessageListener implements Runnable { @Override public void run() { try { String line; while ((line = in.readLine()) != null) { messageArea.append(line + "\n"); } } catch (IOException e) { JOptionPane.showMessageDialog(Client.this, "Failed to receive message from the server."); e.printStackTrace(); } } } public static void main(String[] args) { Client client = new Client(); } } ``` 以上就是基于Java的Socket通信实现多人多线程聊天室的大致代码，客户端采用图形界面并有加入聊天室和退出聊天室的选项。
