    Default Iterator next import class?

    Hi.

    I am creating a java applet, but I dont think I am importing the correct classes:


    import java.applet.*;
    import java.io.*;
    import java.net.*;
    import java.awt.event.*;
    import java.util.regex.Pattern;
    import java.util.regex.Matcher;
    import java.util.*;
    import java.util.ListIterator;
    import java.util.List;
     
     
                       Map<String, List<String>> headers = connection.getHeaderFields();
                        List<String> values = headers.get("Set-Cookie");
     
                        String cookieValue = null;
                        for (Iterator iter = values.iterator(); iter.hasNext(); ) {
                             String v = values.next();
                             if (cookieValue == null)
                                 cookieValue = v;
                             else
                                 cookieValue = cookieValue + ";" + v;
                        }

    error:

    httpc.java:180: cannot find symbol
    symbol : method next()
    location: interface java.util.List<java.lang.String>
    String v = values.next();



    Which class am I missing? thanks.

    Um, you need to review how to set up a class. If this is your entire code, you should have a look at how to declare a class (not one your importing, but the one you are creating) and really the basics of JAVA in general. I don't even know how to help you with this.

    This is not my entire code!

    I only included the relevant snippets, these two line in particular are not working:


    for (Iterator iter = values.iterator(); iter.hasNext(); ) {
    String v = values.next();

    for (Iterator iter = values.iterator(); iter.hasNext(); ) {
    String v = iter.next();

    Fixed the error with:

     String v = iter.next().toString();

    I assumed the code would work because it was directly taken from Cookie Support.

    Thanks for the help, much appreciated
