第一个发送

public class May {
    public static void main(String[] args) {
//        单线程程序
        try  {
            ServerSocket socket = new ServerSocket(2233);//端口号
            Socket soc = socket.accept();
//            读取信息
            BufferedReader br = new BufferedReader(new InputStreamReader(soc.getInputStream()));
            PrintWriter out = new PrintWriter(soc.getOutputStream());
            while (true) {
//            发送
                System.out.println("发送：");
                String msg = new Scanner(System.in).nextLine();
//                SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
                out.println(String.format("[%s]:%s\r\n", "服务器", msg));
                out.flush();
//            接收
                System.out.println(br.readLine());
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

接收信息并回复

public class Max {
    public static void main(String[] args)  {
        try  {
            Socket s = new Socket("localhost",2233);//链接端口号
            String sc = s.getInetAddress().getHostAddress();//获取IP
//            读取信息
            BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
            PrintWriter out = new PrintWriter(s.getOutputStream());
            while (true) {
//            接收
                System.out.println(br.readLine());
//            发送
                System.out.println("发送：");
                String msg = new Scanner(System.in).nextLine();
//                SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
                out.println(String.format("[%s]:%s\r\n",  sc, msg));
                out.flush();
            }

        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

效果
