1 factory method and 2 Abstract Factory)

Simple Factory:

Public class sendfactory {public sender produce (string type) {If ("mail ". equals (type) {return New mailsender ();} else if ("SMS ". equals (type) {return New smssender ();} else {system. out. println ("enter the correct type! "); Return NULL ;}}}

 

public class SendFactory {         public Sender produceMail(){         return new MailSender();      }            public Sender produceSms(){         return new SmsSender();     }  }

 

public class SendFactory {     public static Sender produceMail(){          return new MailSender();    }           public static Sender produceSms(){        return new SmsSender();    }  }

Factory method:

Public Enum type {SMS, mail} public abstract class sender {public static string [] typearray = new string [] {"SMS", "mail"}; Public type T; public String sendername;} class mail: sender {public mail () {This. sendername = "Zhang Fei"; this. T = type. mail ;}}// abstract class sendonemessage {abstract protected sender createsender (type T); Public void send (type T) {sender s = createsender (t); If (S! = NULL) {console. write (S. sendername + "send a message" + sender. typearray [(INT) T] + "message");} else {console. write ("wrong") ;}}/// <summary> // factory method (implemented by inheritance) /// </Summary> class sendonemail: sendonemessage {public sendonemail () {} protected override sender createsender (type T) {If (t = type. mail) {return New Mail () ;}else {return NULL ;}}}

        static int Main()//string[] args        {            SendOneMessage a = new SendOneMessage();            a.send(type.Mail);            Console.ReadLine();            return 0;        }

 

Abstract Factory:

Public abstract class weapon {public string name; Public void description () {console. write ("I am a" + this. name + "\ n") ;}} class sword1: Weapon {public sword1 () {This. name = "wave blade" ;}} class axe1: Weapon {public axe1 () {This. name = "hand axe" ;}} class sword2: Weapon {public sword2 () {This. name = "Aurora sword" ;}} class axe2: Weapon {public axe2 () {This. name = "Crystal Meteor" ;}}// Abstract Factory interface factory {weapon createsword (); weapon createaxe () ;}class weapon1: factory {public weapon createsword () {return New sword1 ();} public weapon createaxe () {return New axe1 () ;}} class weapon2: factory {public weapon createsword () {return New sword2 ();} public weapon createaxe () {return New axe2 ();}}

        static int Main()//string[] args        {            weapon1 w1 = new weapon1();            weapon2 w2 = new weapon2();            w1.CreateSword().Description();            w1.CreateAxe().Description();            w2.CreateSword().Description();            w2.CreateAxe().Description();            Console.ReadLine();            return 0;        }
