SE 310"is a"
e.g. dog is an animal - ANS-inheritance
"has a"
contained in item
***contained object CANNOT EXIST without the existence of container***
e.g. car has a engine, library has books
solid diamond - ANS-composition
"has a"
contained is part of ***collection of items***
e.g. airport has airplanes, library has students
hollow diamond - ANS-aggregation
"uses a"
e.g. car uses a gas station - ANS-dependency
provides an interface to clients, which access elements, rather than the clients directly
accessing the elements. easier for clients to use - ANS-facade pattern
class in which acts as a converter between two classes. - ANS-adaptor pattern
having an abstract class with multiple concrete classes that implement different strategies that
accomplish the same task, but the client will decide which strategy to use. e.g. you can have an
abstract class called compressionStrategy and have the classes zipCompressionStrategy and
rarCompressionStrategy implement from it. this means that when the user is compressing a file,
they get to decide if they want to compress as .zip or .rar - ANS-strategy pattern
divided into abstraction and implementation. you can have an abstract class, and can have
implementation classes that use the abstract class for their specific purpose. any changes in
abstraction will not affect implementation layer, and any changes in implementation layer will not
, affect abstraction layer. e.g. abstract layer: send message; implementation layer: text message,
email - ANS-bridge pattern
- relies on inheritance
- e.g. a main mazegame class with create methods. enchantedmazegame & bombmazegame
inherit from it, and they override the methods of mazegame with features specific to their class -
ANS-factory method
- relies on composition
- e.g. a main mazegame class will take in an input that redirects to a mazeFactory. the main
abstract mazeFactory has abstract methods of all the create methods. there are additional
factories that implement the abstract factory, like enchantedMazeFactory and
bombMazeFactory, and each factory has methods with features specific to that type of maze -
ANS-abstract factory
False. The bridge pattern promotes loose coupling. It's in the definition. Separate the abstraction
from the implementation so the two can vary independently. As long as you don't vary the
interface you can add as many abstractions or implementations without having to modify any
other classes. - ANS-The bridge pattern does not promote loose coupling because the
abstractions are tightly coupled to the implementations by the interface.
The strategy pattern promotes loose coupling. It's in the definition. Separate the client from the
algorithms so the two can vary independently. As long as you don't vary the interface you can
add as many algorithms or clients without having to modify any other classes. - ANS-The
strategy pattern does not promote loose coupling because the clients are tightly coupled to the
algorithms by the interface.
False. The façade pattern promotes loose coupling because if anything changes in the
subclasses that doesn't affect the public interface of the client isn't effected. - ANS-The façade
pattern does not promote loose coupling because the client is tightly coupled to the underlying
sub classes encapsulated by the interface.
the process of taking a complex process and breaking it down into its smaller, simpler parts. -
ANS-Functional Decomposition
refers to one object relying upon another to provide a specified set of functionalities -
ANS-Delegation
refers to the degree to which the elements of a module belong together. - weak strong -
ANS-Cohesion
the manner and degree of interdependence between software modules - ANS-Coupling
An object is a set of responsibilities. - ANS-Conceptual Level View of an Object
