Question

i often have in java projects a lot of small helper(“storage”) classes like
2-Tuple, 3-Tuple, Point, .. (think you know what i mean)
Classes that mostly only have class variables, a constructor and getters/setters.

And in my current project, i wanted to store those small classes, that are often used in a lot of other classes in the project in a seperate package. But i do not really know how to name it (my motherlanguage is not english, but code should be for english readers.)

Hope you can give me an answer on this little questions.

Greetings

Answer 1

Different people would name these differently as the names are a matter of personal choice.

A few options:

1. If the storage classes conform to the Javabeans conventions, you could add the suffix “Bean” eg PointBean

2. I have also seen a suffix of “DO” or “VO” being used to denote a “data object” or “value object”. eg PointDO

3. You could leave the class name as is eg Point. However if you feel that it does not convey the fact it is a storage class, try to make the package name convey that fact eg
   com.xyz.valueobjects.Point
   or
   com.xyz.dataobjects.Point
   or
   com.xyz.storage.Point

Personally I like to use style #3.
