在Java中，Socket和ServerSocket是进行网络通信的重要类。以下是一些使用Socket和ServerSocket的实例：

1. 客户端连接服务器

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

public class Client {
    public static void main(String[] args) {
        try (Socket socket = new Socket("localhost", 8080);
             BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream())))) {

String message = "Hello, Server!";
            in.write(message.getBytes());
            System.out.println("Message sent to server.");

} catch (IOException e) {
            System.err.println(e.getMessage());
            e.printStackTrace();
        }
    }
}
```

2. 服务器端监听客户端连接

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

public class Server {
    public static void main(String[] args) throws IOException {
        try (ServerSocket serverSocket = new ServerSocket(8080);
             Socket socket = serverSocket.accept();) {

System.out.println("A client has connected to the server.");

BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()))));
            PrintWriter out = new PrintWriter(socket.getOutputStream(), true));

// Read from client and write to server
            String messageFromClient = in.readLine();
            System.out.println("Message received from client: " + messageFromClient);

// Write to client
            String responseToClient = "Hello, Client! You sent: " + messageFromClient;
            out.println(responseToClient);
            System.out.println("Response sent to client.");

} catch (IOException e) {
            System.err.println(e.getMessage());
            e.printStackTrace();
        }
    }
}
```

以上就是使用Java Socket和ServerSocket进行网络通信的基本实例。
