Answer / Tejveer Singh
List and Set are interfaces in Java that represent collections of elements. However, they have some differences:
1. Duplicate elements: A List can contain duplicate elements, while a Set cannot (unless it is a specific type like HashSet).
2. Ordered or unordered: A List maintains the order of its elements, while a Set does not.
3. Implementation: Lists implement the List interface and are implemented using various data structures like arrays, linked lists, and resizable arrays (ArrayList), while Sets implement the Set interface and are typically implemented as hash sets or tree sets.
