Question

I have a class file which when i compile shows me Null pointer exception in a particular line all the time. I handled null check as below.

108    doc = Jsoup.parse(html, brandUrl);

109    Element div = doc.getElementById("eventTTL");
110    String attr = div.attr("eventTTL");
111    Date closingDate = new Date(Long.parseLong(attr));
112    Elements mainForm = doc.select("div#main-form");
113    Elements mainDivs = mainForm.select("DIV");

java.lang.NullPointerException
at com.textT.at.Chickyur.main(Chickyur.java:110)

if(div != null)
String attr = div.attr("eventTTL"); 

 Also tried 
 if(div.attr("eventTTL") != null)
 String attr = div.attr("eventTTL"); 

Still i keep getting the exceptions. What is wrong? any thoughts?

Answer 1

I can’t tell by the code posted above exactly how your code is structured, but this should fix the NullPointerException:

Element div = doc.getElementById("eventTTL");
String attr = "";

if(div != null)
    attr = div.attr("eventTTL");

If you continue getting Exceptions after that, I would guess the issue is elsewhere in the code and you need to update your example.
