java聊天软件源码

以下是一个简单的Java聊天软件的源代码，希望对你有所帮助：

Client.java

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

public class Client {
    public static void main(String[] args) throws IOException {
        Socket socket = new Socket("localhost", 8000);
        System.out.println("Connected to server");

        BufferedReader input = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        PrintWriter output = new PrintWriter(socket.getOutputStream(), true);

        BufferedReader userIn = new BufferedReader(new InputStreamReader(System.in));

        String userInput;
        while ((userInput = userIn.readLine()) != null) {
            output.println(userInput);
            System.out.println("Server: " + input.readLine());
        }

        socket.close();
    }
}

Server.java

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

public class Server {
    public static void main(String[] args) throws IOException {
        ServerSocket serverSocket = new ServerSocket(8000);
        System.out.println("Server started");

        Socket clientSocket = serverSocket.accept();
        System.out.println("Client connected");

        BufferedReader input = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
        PrintWriter output = new PrintWriter(clientSocket.getOutputStream(), true);

        String inputLine;
        while ((inputLine = input.readLine()) != null) {
            System.out.println("Client: " + inputLine);
            output.println("Server received message: " + inputLine);
        }

        clientSocket.close();
        serverSocket.close();
    }
}

这个聊天软件是使用Java的Socket API实现的，其工作原理是一个客户端连接到服务器，并且通过输入输出流发送和接收消息。这个程序只是一个简单的示例，你可以根据自己的需求进行修改和扩展。
