1. private constructor
2. static getInstance
3. syncronized..waste a lot of time
4. double check..modified syncronize, so time-waste might occurs only when first time the instance construct

Initial Design:
diagram.JPG
But now some new functionality should be added, for example: we need some of the ducks to FLY.

First Design:
聽(tīng)聽(tīng)聽(tīng)We add a method fly() into the Duck class. It seems worked, but something went horribly wrong because not all ducks can fly. so....

Second Design:聽(tīng)Using inheritance and polymorphism
聽(tīng)聽(tīng)聽(tīng)Always override the fly() mehtod in the subclass where needed.

test.JPG
聽(tīng)聽(tīng)聽(tīng)

聽(tīng)聽(tīng)聽(tīng)Drawbacks:聽(tīng)Everytime a new duck is added, you will be forced to look at and possibly override fly() and quack(). so is there a cleaner way of having only some of the duck types fly or quack?

Third Design: Using interface!
聽(tīng)聽(tīng)聽(tīng)test1.JPG
Drawbacks: It completely destroy code reuse for those behaviors.

1. Design Principles: Identify the aspects of your application that vary and separate them form what stays the same!
聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng) which means Encapsulate the parts that vary!
2. Design Principles: Program to an interface, not an implementation! (interface here means supertype! including interface
聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)聽(tīng)and abstract class!.. making use of the polymorphism functionality).

The Definition聽(tīng)of Strategy Pattern:聽(tīng)The聽(tīng)Strategy Pattern defines a family of algorithms, encapsulates each one, and makes them intercahgeable. Strategy lets the algorithm vary indepanedtl from client聽(tīng)that use it
聽(tīng)
Problems:
1. It's weird to have a class that's jast a behavior: classes represent things both have state and methods. a flying behavior might have instance variables representing the attributes for the flying behavior.
2.聽(tīng)Be care聽(tīng)of聽(tīng)Over-Design: implement your code first, then refractoring!
