A style of class that is a frequent complement to NOJOs (introduced in my previous article) are classes with only static methods. They might be called SomethingUtil or SomethingHelper.
People will often know what you mean if you say "a Utils" class, so I won't propose anything different here. I had wanted to propose a catchier name - SOJOs (Static Only Java Object) but the acronym (with a completely different meaning) is already taken by the SOJO project. In a comment on my NOJO article, John Q Public said he uses the term "function buckets" and I'm sure he's talking about the same thing.
Why do people write Utils classes?
If you have NOJOs then your methods have got to go somewhere. People who prefer the NOJO style often like to create static methods on Utils classes for those methods.
Are Utils classes a Good Thing?
Again, left as an exercise for the reader. An article from my old blog might help to hint about my views (although it is not specifically about this subject) without me having to stay up all night writing more. It seems like people aren't shy about expressing their opinions in comments - some of which I completely agree with, so I'll leave it as an exercise for comment writers as well as the reader (cheeky, I know).
In defence of my previous article
I didn't make any judgements in my previous article - mostly through lack of time but also because I want the term NOJO to be understood without being confused with whether it's any good or not. I am merely making an observation and suggesting a name for a thing I see frequently, that is poorly served by current names. I found it interesting how many people suggested that there was already a term for NOJO but none of their suggestions were entirely accurate.
