Cannot use Iterable<Double> because Double is a final class about lambdaj HOT 2 CLOSED

You are just misusing the lambdaj API. minFrom() is intended to create a proxy 
of a
list of object in order to find the minimum value on a give property of those 
objects
like in the following example:

Integer age = minFrom(persons).getAge();

To achieve the result you wanted you should use the min() method instad, as it 
follows:

Double minimum = min(numbers);

I hope this helps

Mario,

you are right. I haven't been aware of min(...).
