- 5. Abstract Factory - Intent Provide an interface for creating families of related or dependent objects without specifying their concrete classes. 以同⼀一個介⾯面來來建立⼀一整族相關或相依的物件，不需 點明個物件真正所屬的具象類別 A.K.A: Kit 5
- 6. Abstract Factory • system should be independent of how its products are created, composed, and represented. • system should be configured with one of multiple families of products. • reveal just their interfaces, not their implementations. 6
- 7. interface : declares operations that create abstract objects implements the operations to create concrete objects interface of the products objects created by Concrete Factory implementation of AbstractProduct
- 8. Abstract Factory • Isolate concrete class: hiding product class name, not in client code • Easy to exchange product family: change factory only • Consistency • Singleton factory: one and only one 8

- 15. Builder
- 16. Builder - Intent Separate the construction of a complex object from its representation so that the same construction process can create different representations 16
- 17. interface: create parts of a product construct and assemble parts retrieving product using builder to construct parts
- 19. Builder • Vary product’s internal representation: hide representation and internal structure of product and how the product get assembled • Isolates codes for construction and representation: hide implementation, easy to exchange • One step -> step-by-step 19
- 22. Abstract Factory v.s Builder • For constructing complex objects • Family v.s step-by-step 22
