Exploring the factory method design pattern

The factory method design pattern allows subclasses to determine which class to create. This is achieved by removing details about which class to create away from the framework. Instead, the subclasses are given the responsibility for object creation. This design pattern is useful when the framework is unaware of what is to be instantiated.

We will look at an example use case, the UML class diagram, and the source code that's necessary to implement the factory method design pattern for this scenario.

Use case

To demonstrate the factory method design pattern, we will create a Mower Selection Helper implementation. The system will provide helpful information to aid users in their...
