以下是一个简单的Socket通信的Java示例，分为客户端和服务端。

客户端（ServerSocketClient.java）：
```java
import java.io.;
import java.net.;

public class ServerSocketClient {
public static void main(String[] args) {
try (Socket socket = new Socket(“localhost”, 1234));
{
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream())));
PrintWriter out = new PrintWriter(socket.getOutputStream(), true));

        System.out.println("客户端：读取信息");
        String inputLine;
        while ((inputLine = in.readLine()) != null) {
            System.out.println("客户端：输入：" + inputLine);
        }
        System.out.println("客户端：写入信息");
        out.println("服务端：你好，客户端！");
        System.out.println("客户端：关闭连接");
        out.close();
        in.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

}

2. 服务端（ServerSocket.java）：
```java
import java.io.*;
import java.net.*;
public class ServerSocket {
    public static void main(String[] args) {
        try (ServerSocket serverSocket = new ServerSocket(1234)); 
        { 
            Socket socket = serverSocket.accept(); 
            System.out.println("服务端：连接建立，客户端：" + socket.getRemoteSocketAddress()));
            BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()))); 
            PrintWriter out = new PrintWriter(socket.getOutputStream(), true));
            System.out.println("服务端：开始接收信息");
            String inputLine;
            while ((inputLine = in.readLine()) != null) {
                System.out.println("服务端：收到客户端信息：" + inputLine);
                // 这里可以处理业务逻辑
            }
            System.out.println("服务端：向客户端发送信息");
            out.println("客户端，你好，服务端！");
            System.out.println("服务端：关闭连接");
            out.close();
            in.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
