Did you look at documentation? See this  http://developer.joomla.org/platform-manual.html, in special  http://developer.joomla.org/manual/ch01s04.html .

The manual is a bit simple, but works like is explained on it. You must have sure that your classes, folders and filenames follow one specific pattern.

You can also look at source of JPlatform. In special this file  https://github.com/joomla/joomla-platform/blob/staging/libraries/import.php  and, about Joomla "J", this specific line here  https://github.com/joomla/joomla-platform/blob/staging/libraries/loader.php#L279 .

The benefit of the autoloader is that you don't have to remember to
use JLoader::register() or jimport for every dependent class for the
class you are writing. As long as the auto loader can find the class
name and file name based on the conventions, the dependent classes are
loaded for you using the built-in lazy loading mechanism of php.
Performance wise, it is just as good to manually register the classes
using JLoader::register(). It's just more work. Mark

Thanks Mark

Means if Jloader class execute at once then no need to jimport in each files.

and as you said i think this Jloader class do all work in backend process.

or we can also write some function then call through that Jloader class? 

Thnaks,

If you aren't worried about memory usage, you could simply use
JLoader::register() to register all of your classes once at startup.
As I understand it, the classes aren't loaded until they are needed,
so the only overhead is the ram to keep track of the class list. Mark

I just thought I chime in here regarding the naming convention. You don't have to use the default "J" prefix anymore. If you registar your prefix with JLoader and specify what directory to look in then any prefix will work.
