public class NPFactoryH

extends java.lang.Object

implements NPFactory

This class holds the factory methods for the NP class. Users can use this class to create instances of NP objects with their desired parameters. A static keyword is used to instantiate an instance of NPFactoryH so that the static variable "factory" in this class will have access to the create methods. Users can also create instances of NPH directly using the constructors of the NP class. The primary reason of the creation of this class is to allow the NP class, which implements the NP interface to have constructors while being able to implement all the methods in the interface.
