It should be used when there is a system that creates objects, but how those objects are created should be hidden from view. In particular, it is used when applications have families of objects. The application should be able to choose which of a selection of families it wants to use. The abstract factory pattern can ensure that family groups are used together. Say, for example, there is an application that builds bicycles. First, all of the individual bike parts need to be built. The wheels, handlebars, gear and frame, and so on, need to be made, and not just any old parts. To make a mountain bike, for example, you need wheels with a strong frame and thick tires. Mountain bikes also need straight handlebars, so these different parts are examples of a family of objects that need to be made together. The process of making a mountain bike…
