Fundamental difference between List and Set in Java is allowing duplicate elements. List in Java allows duplicates while Set does not allow any duplicate.
more precisely singly-linked list, is also a data structure that can be used to store collection of elements. It is made up of a sequence of nodes and each node has a reference to
Set implementations:HashSet,LinkedHashSet,TreeSetetc. 4) List allows any number of null values. Set can have only a single null value at most. 5)ListIteratorcan be used to traverse a List in both the directions(forward and backward) However it can not be used to traverse a Set. We ca...
