本文提供了一个简单的Java Socket通信示例，包括服务器端和客户端的实现代码，演示了如何通过Socket进行基本的数据交换。

服务器端代码：

package socket;

import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class Server {
   public static int port = 8088;
    public static String ip = "";

    public static void main(String[] args) throws IOException {
        //①启动服务器
        ServerSocket server = new ServerSocket(port);
        System.out.println("server running...");
        //②监听Socket
        Socket socket = server.accept();
        //③IO流
        BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        PrintWriter pw = new PrintWriter(new OutputStreamWriter(socket.getOutputStream()));

        String client = null;
        //如果接收到客户端的exit信号则关闭Socket
        while(!"exit".equalsIgnoreCase(client = br.readLine())){
            System.out.println("from client say:"+client);
            pw.println("server get your info :" +client);
            pw.flush();
        }

        br.close();
        pw.close();

        socket.close();
        server.close();
    }
}

客户端代码:

package socket;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;

public class Client {

   public static void main(String[] args) throws IOException {
        //连接服务器
        Socket socket = new Socket(Server.ip,Server.port);
        System.out.println("client running...");

        System.out.println("-----insert your info:");
        //用户在控制台输入向服务器发送的信息
        BufferedReader brConsole = new BufferedReader(new InputStreamReader(System.in));
        //IO流
        PrintWriter pw = new PrintWriter(socket.getOutputStream());
        BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));

        String server = null;
        //如果用户输入exit则关闭Socket
        while(!"exit".equalsIgnoreCase(server = brConsole.readLine())){
            pw.println(server);
            pw.flush();
            System.out.println("from server say:"+br.readLine());
        }
        //当用户输入exit时，把exit信息发送给服务器，服务器关闭当前Socket
        pw.println(server);
        pw.flush();
        pw.close();
        brConsole.close();
        br.close();
        socket.close();
    }
}
