public class PPFactoryH

extends java.lang.Object

implements PPFactory

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