/**
* The Factory Method is a creational design pattern which uses factory methods to deal with the
* problem of creating objects without specifying the exact class of object that will be created.
* This is done by creating objects via calling a factory method either specified in an interface
* and implemented by child classes, or implemented in a base class and optionally overridden by
* derived classes—rather than by calling a constructor.
*
* <p>Factory produces the object of its liking.
* <p>
* <p>Factory produces the object of its liking.
* The weapon {@link Weapon} manufactured by the
* blacksmith depends on the kind of factory implementation it is referring to.
