Is there any more difference between a Thread and Runnable apart from
--Thread is a class which encapsulates a thread of execution in a mutithreading system.
--Runnable is an interface used for multithreading purpose in java and also because java does not support multiple inheritance.
For Eg: class A extends Thread , B {
}
is not possible , so use
class A extends B implements Runnable{
}
?

If you are doing stuff with reflection, e.g. loading a class that extends Thread via defineBytes(...) , and there is a security manager, then you will run into trouble because the default thread constructor calls setPriority. In that case, it is better to use Runnable.

Chakk de,
