Scripts and Programming

Ok, so here are my classes and interfaces:

[code]public interface I_LinkedStack extends Iterable
public LinkedStack implements I_LinkedStack
-- private static class Node
-- private class LinkedListIterator implements java.util.Iterator
public Postfix[/code]

Postfix is a class with the following methods:

[code]public String iterableToString(Iterable stack)
public String infixToPostfix(String infixExpression)
public int evaluatePostfix(String postfixExpression)[/code]

Everything is working fine with the exception of one thing. In my evaluatePostfix method I call iterableToString in order to print a stack declared locally within evaluatePostfix. Like this:

[code]LinkedStack stack = new LinkedStack();
[...]
System.out.println(this.iterableToString(stack));[/code]

But I'm getting the following error:

[code]iterableToString(java.lang.Iterable) in Postfix cannot be applied to (LinkedStack)[/code]

Why? LinkedStack is an iterable type, and Integer is just fine for T. It might also be worth noting that it compiles if I try to pass it String, Integer, or any other class like that.

[b]Challenge:[/b] Use the Google Maps API to create an interactive map or mashup.

The Google Maps API has been around for a few years and is one of the more frequently used APIs offered by Google. The benefits of using the Google Maps API are obvious: it's free, simple to use, and (most importantly) visually impressive. In order to use the Google Maps API, you only need a basic understanding of HTML, CSS and JavaScript – so almost anyone involved in web development can find ways to use it!

[b]Ideas:[/b]
- Mark Your House
- Include your Avatar in your marker
- Create custom markers

[b]Ideas for Advanced Users:[/b]
– try adding the various map overlays (Traffic, StreetView, etc.)
– explore the GMap2() class methods (enableDoubleClickZoom, enableGoogleBar, etc.)
– try adding more than one location and marker

[b]Example:[/b] Adding a map to your website.
[code]

[/code]

In the example above, you will see that we create a 500×500 pixel map that has centered on the White House.

We use the JavaScript method getElementById() to locate the DIV element where the map will be rendered. We then provide the Google Maps API with the appropriate address for our map location, and finally place a marker on the map with an info window listing our company for the world to see.

To build your own map you need to do two things:
(1) you need to get your own API “key” [url=http://code.google.com/apis/maps/signup.html]here[/url] (If you're just testing this out on a file:// or localhost address, you don't need a key), replacing the “XXXXXXXXXX” in my example
(2) you need to replace the White House address with your own

[i](Note: Be sure to use the onload() and onunload() event handlers on the BODY tag – the map won't work correctly without them!)[/i]
