使用Jsoup提取评论

Question

I am trying to extract comments and found this code here...I am running this through Netbeans...When i ran this code it is throwing an error...

import org.jsoup.Jsoup;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
import org.jsoup.nodes.Document;

public class Main {

public static void main(String[] args) {
      Document doc = Jsoup.connect("http://www.zomato.com/mumbai/starbucks-coffee-fort").get();
      Elements div = doc.select("div.res-review-body > div > p");
        for (Element paragraph : div) {
           System.out.println(paragraph.text());
}
}

}

Error Details:

java:15: unreported exception java.io.IOException; must be caught or declared to be thrown Document doc = Jsoup.connect(" http://www.zomato.com/mumbai/starbucks-coffee-fort ").get();

Answer 1

If you are using Netbeans you will be certainly able to see a red color light bulb in front of this line.

Document doc = Jsoup.connect("http://www.zomato.com/mumbai/starbucks-coffee-fort").get();

click that bulb and it will show you the options. What you are missing is a try catch block for java.io.IOException.

Edit: - By clicking on that bulb it will give you option to surround the block with try and catch.
