Java: is there a map function?

Question

I need a map function. Is there something like this in Java already?

(For those who wonder: I of course know how to implement this trivial function myself...)

Answer 1

This is another functional lib with which you may use map: http://code.google.com/p/totallylazy/

sequence(1, 2).map(toString); // lazily returns "1", "2"
