Java: Set Interface and HashSet
Answer
Use a Set when you need to ensure uniqueness and don't care about order.
A Set is best when you need to prevent duplicates, such as storing unique user emails. A List is better for ordered collections or when duplicates are allowed, like a shopping cart where the same item can appear multiple times.
