String s=httprequest.sendget ("Https://www.quora.com/search", "q=have%20you%20ever%20done%20the%20nofap% 20Challenge? ");
Document doc = Jsoup.parse (s);
list<string> Answer_url = new arraylist<string> ();
Elements Ctag = Doc.select ("Div.pagedlist_item");
System.out.println (s);
for (element Question:ctag) {
	element href = question.select ("A.question_link").
	if (href!= null) {
		System.out.println ("www.quora.com" + href.attr ("href"));
		Answer_url.add ("https://www.quora.com" + href.attr ("href"));
	}
for (String url:answer_url) {
	//url = "http://www.quora.com/ What-is-the-craziest-thing-you-have-ever-said-or-done-at-an-interview-and-still-got-the-job ";
	String page = httprequest.sendget (URL, "");
	SYSTEM.OUT.PRINTLN (page);
	Solveanswerpage sol = new Solveanswerpage ();
	list<string> iRes = sol.solve (page);
	
	for (String tem:ires) {
	//	System.out.println (TEM);
	}
	//break;
}
System.out.println ("Done");

public class Solveanswerpage {public
	list<string> solve (String s) {
		list<string> res = new ArrayList <String> ();
		Document doc = Jsoup.parse (s);
		Elements answers = Doc.select ("Div.pagedlist_item");
		System.out.println (Answers.size ());
		for (Element answer:answers) {
			
			res.add (Answer.text ());
			
			System.out.println (Answer.text ());
		}
		return res;
	}
