Get different objects through factory factory in simple Factory mode, but with one obvious drawback-simple Factory mode systems are hard to scale!Once you add a new product, you have to modify the simple factory method, which makes the

We create different objects with Factory.For example, if you create an interface for a car, create an object that implements the interface through the Factory factory, and create different objects based on our choices.Create a car interface ///
