Q: Choose the class that can hold multiple equal objects in an ordered way.
options: Map, Collection, List, Set, Vector
The given answer is List. I believe answer should be Vector as question is asking for a class not interface. List is an interface that is implemented in Vector class.

As the question is worded, you are correct. The question asked for a class so List shouldn't be a valid answer.

You're right, List is an interface. And I also agree with you that answer should have been Vector.
