A HashSet object contains the non duplicate values, you can say the HashSet object is the collection of the objects that contains no duplicate elements, and whose elements are in no particular order.(source:authorcode)

In computer science, a set is an abstract data structure that can store certain values, without any particular order, and no repeated values. It is a computer implementation of the mathematical concept of a finite set. Unlike most other collection types, rather than retrieving a specific element from a set, one typically tests a value for membership in a set.(source: wikipedia)
