import javax.script.ScriptEngineManager;
import java.io.FileReader;

public class Main {

    public static void main(String[] args         


        

Answer 1

According to the documentation:

The window object represents an open window in a browser.

Since you are not executing your script in a browser, the window object is not defined.

You can read the URL using the URL/URLConnecion classes and feed it to the ScriptEngine. There is a tutorial here.
