Delphi like sets

[Vojta]

Please, how can I create Delphi like sets in Java?

In Delphi I could define set:

TAnimal = (aDog, aCat, aHorse, aSheep);
TAnimals = set of TAnimal;

And then for example:

Animals := [aDog, aCat];
if aDog in Animals then ...

Can I do sometling similar in Java? How?

Thank you a lot! Vojta

I don't know Delphi, and you didn't provide enough examples to guess at
the semantics, but you could probably do what you intend with either Java
1.5's enum, or the Set interface.

Thank you Oliver! EnumSet it the thing I was looking for
