给出代码

由于这个网络版的猜拳游戏涉及到很多方面，需要的代码量比较大，这里只提供一个简单的代码框架，供参考。

1. 服务器端代码框架：

import java.net.ServerSocket;
import java.net.Socket;

public class GameServer {
    private ServerSocket serverSocket;
    private Socket clientSocket;

    public GameServer(int port) {
        try {
            serverSocket = new ServerSocket(port);
            System.out.println("Server is running on port " + port);
        } catch (Exception e) {
            System.err.println("Error: " + e.getMessage());
        }
    }

    public void start() {
        while (true) {
            try {
                clientSocket = serverSocket.accept();
                // 处理客户端请求
                new ClientHandler(clientSocket).start();
            } catch (Exception e) {
                System.err.println("Error: " + e.getMessage());
            }
        }
    }

    public static void main(String[] args) {
        GameServer server = new GameServer(12345);
        server.start();
    }
}

class ClientHandler extends Thread {
    private Socket clientSocket;

    public ClientHandler(Socket socket) {
        this.clientSocket = socket;
    }

    @Override
    public void run() {
        // 处理客户端请求
    }
}

2. 客户端代码框架：

import java.net.Socket;

public class GameClient {
    private Socket socket;

    public GameClient(String serverIp, int serverPort) {
        try {
            socket = new Socket(serverIp, serverPort);
            System.out.println("Connected to server " + serverIp + ":" + serverPort);
        } catch (Exception e) {
            System.err.println("Error: " + e.getMessage());
        }
    }

    public void start() {
        // 处理用户界面
    }

    public static void main(String[] args) {
        GameClient client = new GameClient("127.0.0.1", 12345);
        client.start();
    }
}

这只是一个简单的代码框架，具体的实现还需要根据具体需求来进行设计和开发。
