请教一下JAVA的网络访问的一点逻辑问题

Question

JAVA客户端向服务器发送消息并接受返回的数据 然后把返回的数据再发到服务器上 然后再把返回的数据发到服务器 这样的循环操作要怎么写啊 贴出代码求一个简单的指点啊望各位大神们各不吝赐教啊！！！！

try {
URL url = new URL("http://******/*****/*****?C=" + "s");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setConnectTimeout(5000);
connection.setReadTimeout(8000);
connection.setRequestMethod("GET");
connection.setUseCaches(false);
connection.setDoOutput(true);
connection.setDoInput(true);

    OutputStream outputStream = connection.getOutputStream();
    outputStream.flush();
    connection.getResponseCode();

    InputStream in = connection.getInputStream();
    BufferedReader reader = new BufferedReader(new InputStreamReader(in));
    StringBuilder response = new StringBuilder();
    String line;
    while ((line = reader.readLine()) != null) {
        response.append(line);
    }
    Log.i("返回的数据是 ", response.toString());
    try {
        JSONObject obj = new JSONObject(response.toString());
        JSONArray arr = obj.getJSONArray("info");

        for (int i = 0; i < arr.length(); i++) {
            JSONObject subObj = arr.getJSONObject(i);
            String id = subObj.getString("id");
            String name = subObj.getString("name");
            String ver = subObj.getString("ver");
            Log.i("解析后的数据 ", "id=" + id + ",name=" + name + ",ver=" + ver);
        }
    } catch (JSONException e) {//
        e.printStackTrace();
    }
} catch (IOException e) {
    e.printStackTrace();

}

使用socket通信
建立一个socket

     public static void main(String[] args) {  
        ServerSocket s = null;  
        Socket socket  = null;
        System.out.println("server starting....");
        try {  
            s = new ServerSocket(PORT);  
            //等待新请求、否则一直阻塞  
            while(true){
                socket = s.accept();  
                System.out.println("socket:"+socket);
                //一旦有客户端接入，就创建处理线程
                new ServeOneJabbr(socket);  
            }  
        } catch (Exception e) {  
            try {  
                socket.close();  
            } catch (IOException e1) {  
                e1.printStackTrace();  
            }  
        }finally{  
            try {  
                s.close();  
            } catch (IOException e) {  
                e.printStackTrace();  
            }  
        }
    }  

线程处理

 public class ServeOneJabbr extends Thread{  

    private Socket socket = null;  
    private DataInputStream br = null;  
    private DataOutputStream pw = null;  

    public ServeOneJabbr(Socket s){  
        socket = s;  
        try {  
            br = new DataInputStream(socket.getInputStream());
            pw = new DataOutputStream(socket.getOutputStream());
            start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }  

    @Override
    public void run() {
        int empty_times = 0;
        while(true){
                    //死循环里面写你的业务逻辑处理
                }
        }
}
