The best way to check selector in Jsoup

I have:

Document doc = Jsoup.connect("http://example.com").get();
doc.select(".main li").last().remove();

This is working good if .main li exists, but if it doesn't exist, then this my application crashes.

How can i check if .main li exists?

As per JSoup API for Document and Element.html#select(java.lang.String)‌​, doc.select(String) method returns Elements. So you can check for el.size() to see if it has any elements before deleting the last item.

Elements elements = doc.select(".main li");
if(elements.size() > 0){
   elements.last().remove();
}

or you can check if the last element is not null before removing it:

Element element = doc.select(".main li").last();
    if(element != null){
       element.remove();
    }
