在网络编程中，Java提供了Socket和ServerSocket类来实现TCP连接。以下是一个简单的示例，展示如何创建服务器监听端口，并处理可能的异常。

import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;
public class NetServer {
    public static void main(String[] args) {
        try (ServerSocket server = new ServerSocket(8080)) {
            System.out.println("Server started on port 8080...");
            while (true) {
                Socket client = server.accept();
                System.out.println("Client connected: " + client);
                // Here, you can handle the data sent by client
                BufferedReader inFromClient = new BufferedReader(new InputStreamReader(client.getInputStream())));
                String inputLine;
                while ((inputLine = inFromClient.readLine()) != null) {
                    System.out.println("Received from client: " + inputLine);
                    // Your response goes here
                }
                inFromClient.close();
                client.close();
            }
        } catch (IOException e) {
            System.err.println("Error occurred: " + e.getMessage());
            e.printStackTrace();
        }
    }
}
