请举一个你使用Java实现网络通信的例子。

以下是一个简单的Java网络通信例子，我们创建了一个客户端，它将向服务器发送消息并接收响应。

首先，我们需要创建一个服务器端：

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

public class Server {
    public static void main(String[] args) {
        try (ServerSocket serverSocket = new ServerSocket(8000)); {
            System.out.println("Server is listening on port 8000...");

Socket clientSocket = serverSocket.accept();

System.out.println("Client has connected: " + clientSocket);

// Here you can handle client requests and send responses

} catch (IOException e) {
            e.printStackTrace();
            System.out.println("An error occurred while listening on port 8000.");
        }
    }
}
```

然后，创建一个客户端来发送消息：

```java
import java.net.Socket;

public class Client {
    public static void main(String[] args) {
        String serverIP = "127.0.0.1"; // Replace with your server's IP address
        int serverPort = 8000; // The port where the server is listening

try (Socket socket = new Socket(serverIP, serverPort)); {
            System.out.println("Client has established a connection to the server...");

// Here you can send data to the server and read responses

} catch (IOException e) {
            e.printStackTrace();
            System.out.println("An error occurred while connecting to the server.");
        }
    }
}
```

这段代码将创建一个服务器，监听8000端口。然后创建一个客户端，连接到这个服务器并发送消息。服务器会处理这些请求并返回响应。
