Utility classes are evil? [closed]

Answer 1

Looking back at this question now, I'd say that C# extension methods completely destroy the need for utility classes. But not all languages have such an in-genius construct.

You also have JavaScript, where you can just add a new function right to the existing object.

But I'm not sure there really is an elegant way to solve this problem in an older language like C++...

Good OO code is kinda hard to write, and is hard to find since writing Good OO requires a lot more time/knowledge than writing decent functional code.

And when you're on a budget, your boss isn't always happy to see you've spent the whole day writing a bunch of classes...

Answer 2

I suppose it starts to become evil when

1) It gets too big (just group them into meaningful categories in this case).
2) Methods that should not be static methods are present

But as long as these conditions are not met, I think they are very useful.
