本文介绍了一个简单的客户端与服务端循环发送和接收消息的Java实现案例。客户端不断发送带有计数的消息到本地服务器，然后接收服务器的响应。服务器接受客户端的连接，读取并打印客户端发送的消息，然后发送固定的响应消息。

客户端循环发送消息，服务端循环接收消息

class Client {
    public static void main(String[] args) throws IOException, InterruptedException {
        int i = 0;
        while (true) {
            Socket socket = new Socket("127.0.0.1", 4455);
            OutputStream outputStream = socket.getOutputStream();
            PrintStream printStream = new PrintStream(outputStream);
            Thread.sleep(1000);
            printStream.println("我是客户机，问候服务器  " + i++);

            InputStream inputStream = socket.getInputStream();
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
            String s = bufferedReader.readLine();
            System.out.println(s);
        }
    }
}

class Server {
    public static void main(String[] args) throws IOException {
        int i = 0;
        ServerSocket serverSocket = new ServerSocket(4455);
        while (true) {
            Socket accept = serverSocket.accept();
            InputStream inputStream = accept.getInputStream();
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
            String s = bufferedReader.readLine();
            System.out.println(s);
            OutputStream outputStream = accept.getOutputStream();
            PrintStream printStream = new PrintStream(outputStream);
            printStream.println("我是服务器，问候客服机");
        }
    }
}
