Creational Patterns

Creational Patterns: 

Creational design patterns specifically deal with the process of object creation. They provide solutions and guidelines for creating instances of classes in a flexible, reusable, and maintainable manner. These patterns focus on abstracting the instantiation process, encapsulating it, and often allowing for variations in the way objects are created. This helps in building scalable and adaptable software systems by providing a structured approach to handling object creation challenges.

Singleton Pattern:  ...

Explanation: Ensures a class has only one instance and provides a global point to this instance.

Real World Example: Think of a printer spooler. There should be only one instance managing the print jobs to avoid conflicts.

Factory Method Pattern:

Explanation: Defines an interface for creating an object, but leaves the choice of its type to the subclasses.

Real World Example: Imagine a car manufacturing plant. The assembly line (factory) produces various models of cars, but the specific model is determined by the type of car being assembled.

Abstract Factory Pattern:

Explanation: Provides an interface for creating families of related or dependent objects without specifying their concrete classes.

Real World Example: Consider a GUI library. The abstract factory could define interfaces for creating buttons, text boxes, and windows. Concrete factories would produce specific types of buttons, text boxes, and windows that work together seamlessly.

Builder Pattern:

Explanation: Separates the construction of a complex object from its representation, allowing the same construction process to create different representations.

Real World Example: Think of building a custom computer. You can choose different components like processor, memory, and storage to create a unique computer configuration.

Prototype Pattern:

Explanation: Creates new objects by copying an existing object, known as the prototype.

Real World Example: In graphic design software, you might create a template (prototype) for a logo. Instead of starting from scratch each time, you duplicate and modify the template to create new logos.
