public static void getContentFromUrl(String url) {    HttpClient client = new DefaultHttpClient();    HttpGet getHttp = new HttpGet(url);    while (true) {        try {            HttpResponse response = client.execute(getHttp);            HttpEntity entity = response.getEntity();            String content = null;            String str = null;            if (entity != null) {                content = EntityUtils.toString(entity);                str = new String(content.getBytes("ISO-8859-1"), "UTF-8");            }            sleep(2000);        } catch (IOException | InterruptedException | ParseException e) {            e.printStackTrace();        }    }}
