The creation pattern of design pattern perception

Summary of the creation pattern:

The Earth (customer) needs a nature (product), the nature needs to have a lot of animals (product features), many plants (product features). Nature uses a combination of singleton mode and abstract Factory mode. Animals and plants are created using a simple factory method pattern. To create an animal, for example: In a simple factory encounter the same "person", Directly using the prototype pattern cloning, the law is created by the builder mode.

Public Animal

{

Private String mtype = null;

Public Animal Clone ()

{

...

}

Public String GetType ()

{

return mtype;

}

}

Public Humananimal extends Animal

{

public static Builder ()

{

Public Build Add (String part)

{

}

Public Humananimal Build ()

{

}

}

}

Public animalfactory

{

Private Animal mlastanimal = null;

Public Animal Create (String type)

{

if (Type.equals (Mlastanimal.gettype))

{

return Mlastanimal.clone ();

}

Else

{

Animal Temp=null;

if (type.eaual ("person"))

{

temp = new Humananimal.builder (). Add ("Hand"). Add ("header"). Add ("Foot"). Add ("torso"). Build ();

}

...//other animals slightly

Mlastanimal = temp;

return temp;

}

}

}

Private Class Nature

{

Private list<animal> manimals= new arraylist<animal> ();

Private list<plant> mplants = new arraylist<plant> ();
