How to understand factory class in factory method class??

Question

Design patterns

I'm trying to figure out the factory pattern, but I can't really understand why the Factory is needed.
I'm looking at an example from this site . What is the point of the "ParserFactory" class, if you can just write the same thing in the method by getting rid of the class??

Answer 1

To make it easier to program later. Without understanding what is behind the interface. Everything is on the shelves, predictably structured and predictably behaves.
A long time ago I thought that OOP and patterns were generally only relevant "for large projects". When I stopped thinking like that, I started developing 5 times faster.
