基于Java语言的网络聊天室程序设计，给出代码完成这些要求： 1、使用TCP或UDP协议设计一个客户端程序和一个服务器程序，接收和发送聊天室程序的信息。 2、设计两个界面程序，完成聊天室程序用户发送信息输入和用户接收信息的现实。 3、设计两个文件处理程序，完成聊天双方信息的保存和记录。

很高兴回答您的问题。基于Java语言的网络聊天室程序设计，需要完成以下要求：

1.设计一个服务器程序和一个客户端程序，使用TCP或UDP协议进行通信。

服务器程序：

import java.io.*;
import java.net.*;

public class Server {
    public static void main(String[] args) {
        ServerSocket server = null;
        Socket socket = null;
        BufferedReader in = null;
        PrintWriter out = null;
        try{
            server = new ServerSocket(8888);
            socket = server.accept();
            in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            out = new PrintWriter(socket.getOutputStream());

            String line = null;
            while((line = in.readLine()) != null){
                System.out.println("Received message: " + line);
                out.println("Server received message: " + line);
                out.flush();
            }
        }catch(Exception e){
            e.printStackTrace();
        }finally{
            try{
                in.close();
                out.close();
                socket.close();
                server.close();
            }catch(Exception e){
                e.printStackTrace();
            }
        }
    }
}

客户端程序：

import java.io.*;
import java.net.*;

public class Client {
    public static void main(String[] args) {
        Socket socket = null;
        BufferedReader in = null;
        PrintWriter out = null;
        try{
            socket = new Socket("127.0.0.1", 8888);
            in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            out = new PrintWriter(socket.getOutputStream());

            BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
            String line = null;
            while((line = reader.readLine()) != null){
                out.println(line);
                out.flush();
                System.out.println(in.readLine());
            }
        }catch(Exception e){
            e.printStackTrace();
        }finally{
            try{
                in.close();
                out.close();
                socket.close();
            }catch(Exception e){
                e.printStackTrace();
            }
        }
    }
}

2.设计两个界面程序，一个用于用户输入信息，一个用于显示接收到的信息。

用户输入信息界面：

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;

public class ClientGUI extends JFrame {
    private JTextField textField;
    private JTextArea textArea;
    private BufferedReader in;
    private PrintWriter out;
    private static String name;

    public ClientGUI() {
        JLabel label = new JLabel("Enter your name: ");
        textField = new JTextField(20);
        add(label, BorderLayout.WEST);
        add(textField, BorderLayout.CENTER);
        textField.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                name = textField.getText();
                dispose();
                initChat();
            }
        });
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        pack();
        setVisible(true);
    }

    private void initChat() {
        JFrame frame = new JFrame(name + "'s Chat Room");
        JPanel panel = new JPanel(new BorderLayout());
        textArea = new JTextArea();
        textArea.setEditable(false);
        JTextField textField = new JTextField();
        panel.add(textArea, BorderLayout.CENTER);
        panel.add(textField, BorderLayout.SOUTH);
        frame.add(panel);
        frame.setSize(500, 300);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(EXIT_ON_CLOSE);

        try{
            Socket socket = new Socket("127.0.0.1", 8888);
            in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            out = new PrintWriter(socket.getOutputStream());
            out.println(name);
            out.flush();

            textField.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    String message = textField.getText();
                    out.println(name + ": " + message);
                    out.flush();
                    textField.setText("");
                }
            });

            while(true){
                String message = in.readLine();
                textArea.append(message + "\n");
            }
        }catch(Exception e){
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        new ClientGUI();
    }
}

用户显示信息界面：

import javax.swing.*;
import java.io.*;
import java.net.*;

public class ServerGUI extends JFrame {
    private JTextArea textArea;

    public ServerGUI() {
        textArea = new JTextArea();
        add(textArea);
        setSize(500, 300);
        setVisible(true);
        setDefaultCloseOperation(EXIT_ON_CLOSE);

        try{
            ServerSocket server = new ServerSocket(8888);
            while(true){
                Socket socket = server.accept();
                new ServerThread(socket).start();
            }
        }catch(Exception e){
            e.printStackTrace();
        }
    }

    private class ServerThread extends Thread{
        private Socket socket;
        private BufferedReader in;
        private PrintWriter out;

        public ServerThread(Socket socket){
            this.socket = socket;
            try{
                in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
                out = new PrintWriter(socket.getOutputStream());
            }catch(Exception e){
                e.printStackTrace();
            }
        }

        public void run(){
            try{
                String name = in.readLine();
                while(true){
                    String message = in.readLine();
                    textArea.append(name + ": " + message + "\n");
                    out.println("Server received message: " + message);
                    out.flush();
                }
            }catch(Exception e){
                e.printStackTrace();
            }finally{
                try{
                    in.close();
                    out.close();
                    socket.close();
                }catch(Exception e){
                    e.printStackTrace();
                }
            }
        }
    }

    public static void main(String[] args) {
        new ServerGUI();
    }
}

3.设计两个文件处理程序，完成聊天双方信息的保存和记录。

保存聊天信息程序：

import java.io.*;
import java.net.*;

public class SaveChat {
    public static void main(String[] args) {
        try{
            BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
            String name = null;
            PrintWriter out = null;
            while(true){
                System.out.println("Enter your name: ");
                name = in.readLine();
                if(name.trim().length() > 0){
                    break;
                }
            }
            Socket socket = new Socket("127.0.0.1", 8888);
            out = new PrintWriter(new FileWriter(name + ".txt"), true);
            BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            String line = null;
            while((line = reader.readLine()) != null){
                out.println(line);
            }
        }catch(Exception e){
            e.printStackTrace();
        }
    }
}

记录聊天信息程序：

import java.io.*;

public class RecordChat {
    public static void main(String[] args) {
        try{
            BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
            System.out.println("Enter your name: ");
            String name = in.readLine();
            BufferedReader reader = new BufferedReader(new FileReader(name + ".txt"));
            String line = null;
            while((line = reader.readLine()) != null){
                System.out.println(line);
            }
        }catch(Exception e){
            e.printStackTrace();
        }
    }
}

以上是基于Java语言的网络聊天室程序设计的所有代码，希望对您有所帮助。
