 Creational Design Patterns
|
This Design
pattern is all about class instantiation.
This pattern can be further divided into
class-creation patterns and object-creational
patterns. While class-creation patterns use
inheritance effectively in the instantiation
process, object-creation patterns use
delegation effectively to get the job done.

The Factory Design Pattern delegates the
work of object creation to derived classes of the
interface |
| The Abstract
Factory
is a type of design pattern that is used for creating
groups of dependant instances of classes without
specifying their concrete classes. |
|
| . |
The Builder Design Pattern separates the
creation of an instance of a class from its
representation so that the same creation pattern can be
used for creating different representations of the object. |
| The Singleton Design Pattern makes sure that
at any point of time, there is one and only one instance
of a class present and also provides a global point of
access to the object. |

The Prototype Design Pattern creates new
instances of classes by copying its prototype |
