  • Factory Pattern
  • Problem:
  • If with many different type of return

3. If we want to add contrete classes we must re-open the code -> not closed for modification Solution:

  • Identify the aspects that vary

4. Encaps object creation(Factory) 5.

  • FactoryPattern

6.

  • FactoryPattern

7.

  • Factory Pattern Defined

8.

  • Code Factory Method
  • Il metodocreatePizza il factory methodinvoca un metodo nella stessa classe che in base alla tipologia di oggetti invoca quello nelle sottoclassi

9. Ex:PizzaStore p = new NewYorkStore(); 10. p.createPizza(jjjj); 11.

  • Code Factory

12.

  • Code Pizza
  • Classe usata per creare l'oggetto con tutti i metodi usati per la creazione della pizza

13.

  • Code Pizza Client
