Factory design pattern advantages

Question

Hello

I am aware that factory design patterns help us to create a method to create objects...

I could not understand how client code is not required to change and all similar terms for this design pattern....

can anyone please help me to understand this in detail?

Answer 1

Refer below link :

https://www.geeksforgeeks.org/design-patterns-set-2-factory-method/

Here in both the way, hard-coding is already there.... in first approach, class constructor is having code to decide object type where as in factory design patterns, class static method decided object type....

if I am codder, what could be differentiated for me to change in class constructor or class method... code change is required at all in case of new addition of object type.... what benifit I could get by defining objects type instantiation into a class method...
