Java Enums can have behavior?

Question

In Java, an Enum can do the great things that Enums do, but can also have methods (behavior and logic). What advantage does that have over using a class using an enum? Simple ex

Answer 1

In our project, we're using Enums for a few things, but perhaps most prominently for i18n purposes - each piece of shown text is given an Enum. The Enum class has a String-returning method that inspects the Locale that is being used, and picks the correct translation from a collection of translations on runtime.

This serves as a dual-purpose - you get code completion from your IDE, and also never forget to translate a string.

The usage is very simple, to the point that it's almost rendundant to give an example, but here's how one might use the translation-enum

System.out.println(Translations.GREET_PERSON.trans()+" "+user.getName());

Or, if you want to be fancy, have the Enum accept arguments, which will, with some magic string manipulation, be inserted in a marked position in the translations string

System.out.println(Translations.GREET_PERSON.trans(user.getName());
