  1. 1-Strategy Pattern-

    Patterns [blank_start]recur[blank_end](5) in many applications
    [blank_start]Encapsulate[blank_end](11) what varies
    Favor [blank_start]Composition[blank_end](11) over inheritance
    Java IO , Networking, Sound [blank_start]APIs[blank_end](4)
    Most patterns follow from OO [blank_start]Principles[blank_end](10)
    High level libraries [blank_start]Frameworks[blank_end](10)
    Pattern that fixed the simulator: [blank_start]Strategy[blank_end](8)
    Program to [blank_start]Interface[blank_end](10), not an implementation
    Patterns go into your [blank_start]brain[blank_end](5)
    Development constant [blank_start]change[blank_end](6)
    Patterns give us a shared [blank_start]vocabulary[blank_end](10)

    2. BEncapsulate
    3. CComposition
    4. DAPIs
    5. EPrinciples

  2. 2-Singleton Pattern-

    It was one of a kind [blank_start]CLASSLOADERS[blank_end](12, 2 words (no space))
    A singleton is a class that manages an instance of [blank_start]ITSELF[blank_end](6, 2 words (no space))
    If you don’t need to worry about lazy instantiation, you can create your instance [blank_start]STATICALLY[blank_end](10)
    Prior to 1,2 this can eat your Singletons [blank_start]GARBAGECOLLECTOR[blank_end](16, 2 words (no space))
    The singleton was embaressed it had no public [blank_start]CONSTRUCTOR[blank_end](11)
    The classic implementation doesn’t handle this [blank_start]MULTITHREADING[blank_end](14)
    Singleton ensures only one of these exist [blank_start]INSTANCE[blank_end](8)
    Singleton provides a single instance and [blank_start]GLOBALACCESPOINT[blank_end](16, 3 words (no space))
    The singleton pattern has one [blank_start]CLASS[blank_end](5)
    Flawed multithreading approach if not using Java 1.5 [blank_start]DOUBLECHECKED[blank_end](13, 2 words (no space))
    One advantage over global variables: [blank_start]LAZY[blank_end](4) creation
    To totally defeat the new constructor, we have to declare the constructor [blank_start]PRIVATE[blank_end](7)
    1. ACLASSLOADERS
    2. BITSELF
    3. CSTATICALLY
    4. DGARBAGECOLLECTOR
    5. ECONSTRUCTOR
    6. FMULTITHREADING
    7. GINSTANCE
    8. HGLOBALACCESPOINT
    9. ICLASS
    10. JDOUBLECHECKED
    11. KLAZY
    12. LPRIVATE
  3. 3-Command Pattern-

    Role of costumer in the command pattern: [blank_start]CLIENT[blank_end](6)
    Our first command object controlled this [blank_start]LIGHT[blank_end](5)
    The waitress was one [blank_start]INVOKER[blank_end](7)
    A command [blank_start]BINDS[blank_end](5) a set of actions and a receiver
    Invoker and receiver are [blank_start]DECOUPLED[blank_end](9)
    Act as the receivers in the remote control [blank_start]VENDORCLASSES[blank_end](13)
    All command provide this: [blank_start]EXECUTE[blank_end](7)
    Carries out a request: [blank_start]RECEIVER[blank_end](8)
    Object that knows the actions and the receiver [blank_start]COMMAND[blank_end](7)
    Another thing command can do: [blank_start]UNDO[blank_end](4)
    Object that knows how to get things done [blank_start]RECEIVER[blank_end](8)
    A command encapsulates this [blank_start]AREQUEST[blank_end](8, 2 words)
    1. ACLIENT
    2. BLIGHT
    3. CINVOKER
    4. DBINDS
    5. EDECOUPLED
    6. FVENDORCLASSES
    7. GEXECUTE
    8. HRECEIVER
    9. ICOMMAND
    10. JUNDO
    11. KRECEIVER
    12. LAREQUEST
  4. 4-Factory Pattern-

    In factory method,each franchise is a [blank_start]CONCRETECREATOR[blank_end](15, 2 words (no space))
    We used [blank_start]OBJECTCOMPOSITION[blank_end](17, 2 words (no space)) in Simple Factory and Abstract Factory and ine-herintance in Factory
    Abstract Factory creates a [blank_start]FAMILY[blank_end](6) of product
    In factory method, who decides which class to instantioate: [blank_start]SUBCLASS[blank_end](8)
    Not a real factory pattern but handy nonetheless: [blank_start]SIMPLEFACTORY[blank_end](13, 2 words (no space))
    Role of PizzaStore in Factory Method Pattern: [blank_start]CREATOR[blank_end](7)
    In abstract factory, each ingredient factoryis a [blank_start]CONCRETEFACTORY[blank_end](15, 2 words (no space))
    When you use new keyword, you are programming to an [blank_start]IMPLEMENTATION[blank_end](14)
    Ethan likes this kind of pizza NYSTYLE createPizza() is a [blank_start]FACTORYMETHOD[blank_end](13, 2 words (no space))
    In factory Method, the PizzaStore and the concrete pizza class all depend on this abstraction [blank_start]PIZZA[blank_end](5)
    When a classs instantiates an object from a concrete class, it’s [blank_start]DEPENDENT[blank_end](9) on that object
    All factory patterns allow us to [blank_start]ENCAPSULATE[blank_end](10) object creation
    1. ACONCRETECREATOR
    2. BOBJECTCOMPOSITION
    3. CFAMILY
    4. DSUBCLASS
    5. ESIMPLEFACTORY
    6. FCREATOR
    7. GCONCRETEFACTORY
    8. HIMPLEMENTATION
    9. IFACTORYMETHOD
    10. JPIZZA
    11. KDEPENDENT
    12. LENCAPSULATE
  5. 5-Adapter Pattern-

    True of false, adapters can only wrap one object: [blank_start]FALSE[blank_end]
    Decorator called adapter this [blank_start]SIMPLEPASSTHROUGH[blank_end](17, 3 words)
    One advantage of facade: [blank_start]DECOUPLING[blank_end](10)
    Priciple that wasn’t as easy as it sounded [blank_start]LEASTKNOWLEDGE[blank_end](14, 2 words)
    An adapter [blank_start]CONVERTS[blank_end](8) an interface
    A [blank_start]DECORATOR[blank_end](9) adds new behavior
    Masquerading as a duck [blank_start]TURKEY[blank_end](6)
    Example that violatest he principle of least knowledge: System.out [blank_start]PRINTLN[blank_end](7)
    If in europe you might need one of these [blank_start]ACADAPTER[blank_end](9, 2 words)
    Adapter with two roles [blank_start]TWOWAY[blank_end](6, 2 words)
    adapter client uses the [blank_start]TARGET[blank_end](6) interface
    Facade still [blank_start]ALLOWS[blank_end](6) low level acces
    Disadvantage of the principle of least knowledge: too many [blank_start]WRAPPERS[blank_end](8)
    A [blank_start]FACADE[blank_end](6) simplifies an interface
    An adapter and a decorator can be said to [blank_start]WRAP[blank_end](4) an object
    1. AFALSE
    2. BSIMPLEPASSTHROUGH
    3. CDECOUPLING
    4. DLEASTKNOWLEDGE
    5. ECONVERTS
    6. FDECORATOR
    7. GTURKEY
    8. HPRINTLN
    9. IACADAPTER
    10. JTWOWAY
    11. KTARGET
    12. LALLOWS
    13. MWRAPPERS
    14. NFACADE
    15. OWRAP
  6. 6-Template Pattern-

    Strategy uses [blank_start]Composition[blank_end](11) Rather than inheritance
    The Template method pattern uses [blank_start]Inheritance[blank_end](11) To defer implementation to other classes.
    Don’t call us, we’ll call you is known as the [blank_start]PrincipleHollywoord[blank_end](19, 2 words)
    A template method defines the steps of an [blank_start]Algorithm[blank_end](9)
    The template method is usually defined in an [blank_start]Abstract[blank_end](8) class
    [blank_start]Optional[blank_end](8) Algorithm steps are implemented by hook methods
    Factory method is a [blank_start]specialization[blank_end](14) of Template method.
    The steps in the algorithm that must be supplied by the subclasses are usually declared: [blank_start]Abstract[blank_end](8)
    A method in the abstract superclass that does nothing or provies deafult behavior is called a [blank_start]Hook[blank_end](4) method
    Big headed pattern: [blank_start]Strategy[blank_end](8)
    The Arrays class implements its template method as a [blank_start]Static[blank_end](6) method
    1. AComposition
    2. BInheritance
    3. CPrincipleHollywoord
    4. DAlgorithm
    5. EAbstract
    6. FOptional
    7. Gspecialization
    8. HAbstract
    9. IHook
    10. JStrategy
    11. KStatic
  7. 7-Observer Pattern-

    Observable is a [blank_start]CLASS[blank_end](5) not a interface
    Ron was both an Observer and a [blank_start]SUBJECT[blank_end](7)
    You say you want to keep your coupling [blank_start]Loose[blank_end](5)
    Implements this method to get notified [blank_start]UPDATE[blank_end](6)
    CurrentConditionsDisplay implements this interface [blank_start]OBSERVER[blank_end](8)
    How to get yourself off the Observer list [blank_start]REMOVEOBSERVER[blank_end](14, 2 words)
    [blank_start]OBSERVABLE[blank_end](10) can manage your observers for you
    Java framework with a lot of observers [blank_start]SWING[blank_end](5)
    You forgot this: [blank_start]SETCHANGED[blank_end](10, 2 words) if you’re not getting notified when you think you should be
    Observers like to be [blank_start]NOTIFIED[blank_end](8) when something new happens
    The WeatherData class [blank_start]IMPLEMENTS[blank_end](10) the Subject interface
    One subject likes to talk to [blank_start]MANY[blank_end](4) observers
    Don’t coun’t on this: [blank_start]ORDER[blank_end](5) for notification
    Subject initially wanted to [blank_start]PUSH[blank_end](4) al the data to Observer down
    Temperature, humidity and [blank_start]PRESSURE[blank_end](8)
    Observers are [blank_start]DEPENDENT[blank_end](9) on the Subject
    Program to an [blank_start]INTERFACE[blank_end](9) not an implementation
    A subject is similar to a [blank_start]PUBLISHER[blank_end](9)
    1. ACLASS
    2. BSUBJECT
    3. CLoose
    4. DUPDATE
    5. EOBSERVER
    6. FREMOVEOBSERVER
    7. GOBSERVABLE
    8. HSWING
    9. ISETCHANGED
    10. JNOTIFIED
    11. KIMPLEMENTS
    12. LMANY
    13. MORDER
    14. NPUSH
    15. OPRESSURE
    16. PDEPENDENT
    17. QINTERFACE
    18. RPUBLISHER
