Java: Set Interface and HashSet
Answer
A Set ensures that all elements are unique, with no duplicates.
The Set interface provides a collection that contains no duplicate elements. For example, when managing a store catalog, using a Set like HashSet ensures that each product ID is unique. If you attempt to add a duplicate product ID, it won't be added.
