* Multithreading Made Easier

* See how easier its to create multithreaded
applications
* Like Java ( I have tried to imitate Java,s
Runnable and Thread )
* You have to do just 4 things :
* 1)Create a class which implements
AObject.Runnable
* 2)Create an object of above class
* 3)Create an object of AObject.Thread passing
it the reference of object in step 2
* 4) Class start() method of AObject.Thread
object
You must be thinking why I didnot try just extending System.
Threading.Thread Because Its a sealed class !!! In near future I will
be adding ThreadGroup Class to AObject Namespace and many more…
Try these codes…
