Answer 16

Correct answer: d

Explanation:

When a get accessor method for a collection-valued cmr-field that has no related values is invoked, the method must return an empty collection. Since the collection in question must not contain duplicate values, the only possible choice is D.

Choice B would be correct if the cmr-field allowed duplicate values.

All the other choices are incorrect.

Please refer to section 10.3.8 of the EJB 2.0 specification for further details.
