import java.io.IOException;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

public class AlexaRank {
public static void main(String[] args) throws IOException {
String site = "www.ngdeveloper.com";
String siteRank = getAlexaRank("www.ngdeveloper.com");
System.out.println("Alexa Rank of " + site + ": \n" + siteRank);
}

public static String getAlexaRank(String siteName) throws IOException {
String baseUrl = "http://www.alexa.com/siteinfo/" + siteName + "";
String alexaRank = null;
Document doc = Jsoup.connect(baseUrl).timeout(0).get();
String globalRank = doc.select("span.globleRank")
.select("strong.metricsUrl").select("strong.font-big2")
.select("strong.valign").not("a").text();
String countryRank = doc.select("span.countryRank")
.select("strong.metricsUrl").select("strong.font-big2")
.select("strong.valign").not("a").text();
alexaRank = "Global Rank: " + globalRank + "\nCountry Rank: "
+ countryRank;
return alexaRank;
}
