Let me give you an example of how I name my classes alphabetically:

  • Car
  • CarHonda (subclass of Car)
  • CarHondaAccord (subclass of CarHonda)

  1. When browsing your files alphabetically in a file explorer, related items appear grouped together and parent classes appear above child classes.
  2. I can progressively refine auto-complete in my IDE. First I type the major type, then the secondary type, and so on without having to memorize what exactly I named the last part of the thing.

My question is why do I hardly see any other programmers do this? They usually name things in reverse or some random order. Take the iOS SDK for example:
