The policy mode is the packaging of the algorithm, which separates the responsibility of using the algorithm from the algorithm itself and delegates it to different objects.

Differences between simple factories and factory methods: Simple factories and factory method patterns look very similar, especially specific factories in simple factories and factory methods. Simple factory, all things have been done in one place. However, the factory method creates a framework for subclasses to decide how to implement it. For example, in the factory method, the OrderPizza method creates a general framework to create pizza. The OrderPizza method relies on the factory method to create specific classes and make actual pizza. It is possible to decide what the actual products manufactured are by inheriting the factory. Simple factories do not have this flexibility.
