Java Naming Convention with Acronyms [closed]

Answer 1

I've seen both of them used in the wild, and Sun seems to go for the DVDPlayer style. I prefer DvdPlayer, though, because that way it is clear where the word boundaries are even if there are multiple consecutive acronyms, as in HTTPURLConnection.

Answer 2

DVDPlayer is the standard, but DvdPlayer is not uncommon.

You more often than not see getId. That's probably due to thinking ID is a shortening of "Identity". It is actually the initials of Identity Document.

HttpURLConnection is often given as an example of mixed convention. However, "http" used as protocol name in a URL should be lower case (although upper case is often accepted).

Answer 3

There is no "correct" answer. Just a set of practices and conventions that better play with your other tools.

Therefore I prefer DvdPlayer. It is more helpful as in Eclipse you can do Ctrl+Shift+T and pick classes by the first letter of each word.

Answer 4

Effective Java seems to prefer DvdPlayer.
