This repository contains examples and explanations for three common design patterns: Singleton, Strategy, and Facade.
The Singleton pattern ensures a class has only one instance and provides a global point of access to it.
- Intent: To control object creation, limiting the number of objects to one.
- Use Case: When only one instance of a class is needed to coordinate actions across a system.
Practical implementation in a real-world product or project that will evolve into a market-ready solution for the company.
The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable.
- Intent: To define a family of algorithms, encapsulate each one, and make them interchangeable.
- Use Case: When you want to define a class that will have one behavior that is similar to other behaviours in a list.
Practical implementation in a real-world product or project that will evolve into a market-ready solution for the company.
The Facade pattern provides a simplified interface to a complex subsystem.
- Intent: To provide a unified interface to a set of interfaces in a subsystem.
- Use Case: When you want to provide a simple interface to a complex subsystem.
