Which interface does not allow duplicates elements?*1 pointA SetB ListC MapD All the answers are true

Solution

The interface that does not allow duplicate elements is A Set.

Here's why:

A Set is a collection that cannot contain duplicate elements. This means that each element in a Set is unique. If you try to insert a duplicate element in Set, the old value would be overwritten.

On the other hand, List and Map interfaces in Java do allow duplicates. A List can contain duplicate elements because each element has a distinct position (index). A Map can have duplicate values but not duplicate keys.

So, the correct answer is A Set.
