Abstract
We don’t always choose the interfaces we work with. For example, I would rather have my car drive me to my destination by itself, without me having to give 100 percent of my attention to the road and the dangerous lunatics driving next to me. It’s the same with software: sometimes you don’t really want a piece of functionality, but it is built into the interface. So what do you do? You make a Null Object.
