Creational Design Patterns abstracts the instantiation of the objects. A simple question may occur to you: Why can't I just create a new Object using the new keyword and be happy thereafter.

- Is my design flexible?
- Will my design promote re-usability?
More often than not, instantiating an object with a new keyword would not result in a good design. We need to see how we can design a system that is both flexible and that promotes reusability. There are totally five creational design patterns which we will see in details one by one. They are,
- Abstract Factory
- Factory Method
