You are creating an A object, and calling it's start() method -- which in turns calls the run() method. This run() method prints the "A".

The A method does set the runnable of the object to B, but since you overridden the run() method of A, it doesn't call it anymore.

You are using the new A(Thread t) constructor for A that it is inheriting from the Thread class. Because of that, without noticing you are starting the run method of the runable Object B instead of the run method of A.
