Java: Set Interface and HashSet
Answer
Use a Set when you need unique elements and don't care about order.
A Set is ideal for collections where uniqueness is crucial, like a product catalog ensuring no duplicate product IDs. Lists, on the other hand, allow duplicates and maintain insertion order, making them suitable for ordered or duplicate-allowed data.
