public class ParticFactoryH

extends java.lang.Object

implements ParticFactory

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