Cannot Find Symbol: Variable >object> of type <Class>?

Question

I'm working through some extra credit projects and when I try to submit it through the auto-check server for my program, it gives me a Symbol Not found error and stops running my code...I'm not entirely sure why because everything seems in scope and spelled correctly.

Any ideas?

public class Chap72 {    
    public static void main(String[] args) throws IOException {

        //User inputs url and name of file to create.
        WebReader instance = new WebReader();

        Scanner console = new Scanner(System.in);
        System.out.println("Enter a URL");
        String url = console.nextLine();
        System.out.println("Enter name of file");
        Scanner location = new Scanner(System.in);
        String fileName = location.next();
        String filename = "PARSEDRESULT.txt";

        try {
            //uses both saveURL for the unaltered HTML
            //uses SaveToURLPage for extracting links.
            instance.SaveToURLPage(url, filename);
            instance.saveURL(instance.Navigate(url), fileName);


        } 
        catch (MalformedURLException e) {
            //catches MalformedURLException
            e.printStackTrace();
        }
    }
}

Error:

error: cannot find symbol
instance.SaveToURLPage(url, filename);
        ^
symbol:   method SaveToURLPage(String,String)
location: variable instance of type Chap72
1 error

I'm not entirely sure why I'm getting this error...

WebReader

    URL pageLocation = new URL(url);
    Scanner in = new Scanner(pageLocation.openStream());
    PrintWriter out = new PrintWriter(fileName);

    while (in.hasNext()) {
        //Cycles through each character
        String line = in.next();
        if (line.contains("href=\"http://")) {
            //if it has an <a> tag, the link is extracted
            int from = line.indexOf("\"");
            int to = line.lastIndexOf("\"");
            out.println(line.substring(from + 1, to));
        }
    }
    in.close(); //closes program
    out.close();
}

}

Answer 1

This error means that there is no such method SaveToURLPage that accepts two String objects as parameters declared in the WebReader class. For any further assistance, you'll need to post the contents (or JavaDoc) of the WebReader class, for us to see.
