What is the difference between Factory and Singleton design Pattern

Question

Accepted Answer

Factory pattern is used to create objects without exposing the instantiation logic to the client, while Singleton pattern ensures a class has only one instance and provides a global point of access to it.

Factory pattern is used to create objects based on a common interface, without specifying the exact class of the object being created.
Singleton pattern restricts the instantiation of a class to one object, ensuring that all requests for the object return the same instance.
Factory pattern allows for the creation of multiple instances of different classes that implement a common interface, while Singleton pattern restricts the instantiation to a single instance of a class.
Example: Factory pattern can be used to create different types of shapes (Circle, Square, Triangle) without exposing the creation logic to the client. Singleton pattern can be used for a Logger class to ensure only one instance is used throughout the application.
