How Does Hashset Internally Works In Java?

Answer»

HASHSET internally uses HashMap to store it's ELEMENTS. But it differs from HashMap on two points.

  • HashSet only stores unique VALUES i.E. no duplicates are allowed.
  • In HashSet we have add(E e) METHOD which takes just the element to be added as parameter not the (key, value) pair.
