Consider a scenario where you need to enforce singleton behavior on a class. How would constructors play a role in ensuring this?
- Constructors are used to create multiple instances, each with a unique ID.
- Constructors are used to enforce thread safety in the singleton pattern.
- Constructors ensure single instance creation by marking the constructor as private and providing a static method to retrieve the instance.
- Constructors play no role in enforcing singleton behavior.
In the singleton pattern, constructors play a crucial role in enforcing the creation of a single instance of a class. To achieve this, the constructor is marked as private to prevent external instantiation, and a static method is provided to retrieve the single instance. This ensures that only one instance of the class exists throughout the application's lifecycle.
