6⟩ Just by seeing the signature of the bean how can you specify whether it is a Stateful or Stateless Session Bean?

The create method in a stateless session bean cannot have arguments, and can only have a single method called create(). While create in Stateful bean can have arguments and could be any method starting with create string eg. create<method>(arg1, arg2,...). Although it is not compiler checked but in stateless bean the ejbPassivate() and ejbActivate() methods has to be empty as these functions are never called by EJB container. As conceptually in stateful session bean we might need to store the clients information hence arguments in create<method> are necessary. While in stateless bean we don't, hence no arguments are necessary. It's intutive isn't. I my life I haven't seen such a futuristic server programming tool as EJB.

16⟩ What are the minimal cost and minimal risksolution?

In binary representation there are some states that are believed to be never occurred due to some particular functionality of a given circuit. If zero output is assigned to such states then it is called minimal risk solution as we are resetting the formidable states which could be occurred accidentally. Another approach is to assigned a don?t care to them so it results in lesser logic and hence is called minimal cost solution.
