Apears like it uses unsual invoking of external package's methods in java?

See more:

Java

in toturials, it say to invoke a method from external package first it is needed to create an object from the class, and then use the period to invoke the method:

1. packageclassname objectname = new packageclassname();
2. objectname.themethod();

but most the libraries found on the net, use the method like this:

import java.io.IOException;  
import org.jsoup.Jsoup;  
import org.jsoup.nodes.Document;  
public class FirstJsoupExample{  
    public static void main( String[] args ) throws IOException{  
                Document doc = Jsoup.connect("http://www.javatpoint.com").get();  
                String title = doc.title();  
                System.out.println("title is: " + title);  
    }  
} 

what is exactly the

Document doc = Jsoup.connect("http://www.javatpoint.com").get();

section? since it doesn't look like creating an object neither apears like invoking a method using an onject name?

What I have tried:

in several toturials on the net, including the oracle toturial, they all use the usual way which is mentionaed at the first:

1. packageclassname objectname = new packageclassname();
2. objectname.themethod();
