Implementing the factory method
The factory method is based on a single function that's written to handle our object creation task. We execute it, passing a parameter that provides information about what we want. As a result, the object we wanted is created.
Interestingly, when we use the factory method, we don't need to know any details about how the resulting object is implemented and where it is coming from. First, we will discuss some real-life applications that use the factory method and then implement an example application that processes XML and JSON files.
Real-world examples
An example of the factory method pattern that's used in real life is in the context of a plastic toy construction kit. The molding material that's used to construct plastic toys is the same, but different toys (different figures or shapes) can be produced using the right plastic molds. This is like having a factory method in which the input is the name of the toy that we want...
