Simple factory versus factory method versus abstract factory

We have talked about three ways to implement the factory pattern, namely, the simple factory, the factory method, and the abstract factory pattern. If you are confused about these three implementations, you are not to be blamed, as there is a lot of overlap between them. Moreover, there is no single definition of these patterns, and experts may differ on how they should be implemented.

The idea is to understand the core concept. At its core, we can say that the factory pattern is all about delegating the responsibility for the creation of appropriate objects to a factory class. If our factory is complex, that is, it should serve multiple types of objects or factories, we can modify our code accordingly.
