Question

The Singleton pattern is a creator design pattern:

O Because it creates other design patterns
O Because it defines a way to implement creating objects
O Because you create it whenever you want

Answer 1

The Singleton pattern is a creational design pattern aimed at ensuring only one instance of a class is created, with a global access point provided. It doesn't create other patterns, nor is it created at will.

Step-by-step explanation:

The Singleton pattern is a design pattern that falls under the category of creational patterns in software engineering. The main purpose of the Singleton pattern is to ensure that a class has only one instance and to provide a global point of access to that instance. This is achieved by:

• Making the constructor private to prevent external instantiation.
• Providing a static method that gives access to the instance when needed.

The option 'Because it defines a way to implement creating objects' is the correct answer to why the Singleton pattern is considered a creational design pattern. It doesn't create other design patterns, nor is it something that you create whenever you want; its instantiation is controlled by the pattern itself to ensure only one instance exists.
