Singleton and Factory Method
Implement the Singleton pattern for unique instances and the Factory Method for flexible object creation.
Intro to Creational Patterns
Welcome to our lesson on Creational Design Patterns! These patterns are all about how objects are created.
They help us manage object instantiation in a way that makes our systems more flexible and robust. Instead of directly creating objects everywhere, we use patterns to control this process.
Singleton: One Instance Only
The Singleton pattern ensures that a class has only one instance and provides a global point of access to that instance.
- It's useful for resources that should be unique, like a configuration manager or a logger.
- To achieve this, the class typically has a private constructor and a static method that returns the single instance.
