在Java中，我们可以使用java.net.Socket和java.net.ServerSocket来实现TCP/IP的网络编程。以下是一个简单的客户端和服务端示例：

1. 客户端（ServerSocketExample.java）:

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

public class ServerSocketExample {
    public static void main(String[] args) throws IOException {
        // 创建服务器Socket对象，绑定到特定IP和端口
        ServerSocket serverSocket = new ServerSocket(8080);

System.out.println("Server is listening on port 8080...");

// 等待客户端连接
        Socket clientSocket = serverSocket.accept();

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

// 客户端发送数据，服务器接收并打印
        BufferedReader in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream())));

String inputLine;
        while ((inputLine = in.readLine()) != null) {
            System.out.println("Received from client: " + inputLine);
        }

in.close();
        clientSocket.close();
    }
}
```

2. 服务端（SocketServerExample.java）：

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

public class SocketServerExample {
    public static void main(String[] args) throws IOException {
        // 创建服务器Socket对象，绑定到特定IP和端口
        ServerSocket serverSocket = new ServerSocket(8080);

System.out.println("Server is listening on port 8080...");

// 等待客户端连接
        Socket socket = serverSocket.accept();

System.out.println("Client connected: " + socket.getInetAddress()));

// 客户端发送数据，服务器接收并打印
        BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()))));

String inputLine;
        while ((inputLine = in.readLine()) != null) {
            System.out.println("Received from client: " + inputLine);
        }

in.close();
        socket.close();
    }
}
```

以上代码实现了TCP客户端和服务端的基本交互。你可以根据实际需求进行修改和扩展。
