What are creational design patterns?

Creational design patterns, as the name suggests, deal with object creation. In some cases, creating objects in a program could involve some extra complexities, and creational design patterns hide these complexities in order to make the use of software components easier. The object creation complexity could be caused by any of the following:

The number of initialization parameters
Required validation
The complexity of acquiring the required parameters

The preceding list could possibly be expanded even more and in many cases, these factors are present not just individually, but in combinations.

We will be focusing on the aspects of creational design patterns in the following sections of this chapter and hopefully, you will have a good understanding of why they are needed and how to use them in real life.
