public class MethodFactoryTest {        public static void main(String[] args) {          SendFactory factory = new SendFactory();          Sender sender = factory.produceSms();        sender.Send();      }  }  interface Sender {      public void Send();  }  class MailSender implements Sender {      @Override      public void Send() {          System.out.println("this is mailsender!");      }  } class SmsSender implements Sender {        @Override      public void Send() {          System.out.println("this is sms sender!");      }  }  class SendFactory {    public Sender produceMail(){          return new MailSender();      }            public Sender produceSms(){          return new SmsSender();      }   }

this is sms sender!
