List can be defined as the type of ordered collection that regulates the elements in the insertion order. It also allows duplicate elements. Inside the List interface, new methods are introduced. Listiterator can insert a List in both forward and backward directions. The list is implemented to store objects that are non-unique according to the instruction order.
Set can be defined as a type of unordered collection in which elements do not maintain any order. All the elements inside a Set are unique. The set interface does not introduce any new interface. Only collection interface methods can be implemented in the Set subclasses. The set can be inserted only in the forward direction with the assistance of an iterator.
