Java - Cannot Resolve Symbol

[Guest]

So I'm using IntelliJ and it seems like a simple problem but all of the onlinet resources haven't fixed my problem.

 

I have this code:

package WorldBoss;import org.jsoup.Jsoup;import org.jsoup.nodes.*;public class WorldBoss {public static void main(String [] args) {Document page = new Jsoup.connect("http://wiki.guildwars2.com/wiki/World_boss").get();Element link = page.select("span").first();System.out.println(link);}}

But I get an error on the connect part of Jsoup.connect saying "Cannot resolve symbol 'connect'"

I have imported the library following this page http://goo.gl/bdAQPt . 

 

My project structure is like this:

What am I doing wrong?

Any help is greatly appreciated.

Thanks

I'm not much help with java but it looks like this guy had the same issue http://stackoverflow.com/questions/3460073/which-packages-must-be-imported

This is why I don't use java, unless your doing android apps java is trash.

 

That said, there's another problem which would only manifest when you got it run: you're passing the URL in flavor of a java.lang.String instead of a java.net.URL. A String would be treated as plain HTML, not as a resource. Fix it as well:

URL url = new URL("http://www.apple.com/pr/");
Document document = Jsoup.parse(url, 3000);

 

you just need to ensure that Jsoup libraries are present in both the compiletime and runtime classpath. When using javac.exe and java.exe, use the -cp argument. E.g. to compile it:

javac -cp .;/path/to/jsoup.jar com/example/YourClass.java

and to execute it:

java -cp .;/path/to/jsoup.jar com.example.YourClass

 

got this from whitephoenix's link

Do I need to add that to my settings somewhere? Typing it into the console gives this.

I get what seems to be the same error

 

Did I do it wrong?

I think the problem is it needs to be

 

new Jsoup().connect("blahblah")

 

 

You're missing the parentheses before the .connect

This solved it, but after surrounding it with a try catch that disappeared, but it worked.

 

Thanks!

No problem, the concept behind it (which I didn't explain earlier because I was in a rush) is that when you only use Jsoup instead of Jsoup(), you're not actually creating a new object because you're not calling the constructor; the compiler thinks you're trying to call a static inner class. 

 

That's why you always have to use 

 

new String();

new ArrayList<>();

 

instead of 

 

new String;

new ArrayList<>;

 

Without the parentheses, you're calling the class, not the constructor.
