HashSet is a concrete class that implements the Set interface in Java. It provides constant-time performance for basic operations such as add, remove, and contains. HashSet also maintains no order of its elements, which is not required by the Set interface. Thus, if you only need the methods provided by the Set interface, and the order of the elements does not matter, HashSet is the best choice.
