List is an ordered sequence of elements. User can easily access element present at specific index and can insert element easily at specified index.

Set is an unordered list of elements. Set does not have duplicate elements.

LIST SET
Duplicates YES NO
Order Ordered Depends on Implementation
Positional Access YES NO

List is an ordered sequence of elements whereas Set is a distinct list of elements which is unordered.

List <E>: An ordered collection (also known as a sequence). The user of this interface has precise control over where in the list each element is inserted. The user can access elements by their integer index (position in the list), and search for elements in the list.

Set<E>: A collection that contains no duplicate elements. More formally, sets contain no pair of elements e1 and e2 such that e1.equals(e2), and at most one null element. As implied by its name, this interface models the mathematical set abstraction.
