“HashSet” class: This class is able to store a set of objects. It also implements the “Collection” interface. This class stores a set instead of list of items. It means that there can be no duplicate elements. The class is named “HashSet” since the algorithm used to implement the set is called a hash table. The package for “HashSet” class is “import java.util.HashSet;” Syntax for defining “HashSet” class: HashSet<Base_type> variable_name = new HashSet<Base_type>(); From the above syntax, “Base_type” represents “Integer”, “Double” or “String”.
