Importing External classes

Hello

Can someone help clarify something for me?

When I point my code to import an external classes such as:

import flash.display.*;

my understanding is that its referencing something within the flash directory to load up the display classes.

In other instances I create a “com.whatever” directory to store other classes that my code can point to.

Well I was running through the Kirupa tutorial (displaying google maps in flash) and I noticed in the code it says “import com.google.maps” the swf works just fine but where is it grabbing the google classes from if I didnt create the directory?

Im fairly new at this so a nice slow, explanation would be greatly appreciated!
