Final answer:
The StaticSet class is a generic class declaration in the StaticSet.java file that uses a HashSet to implement a static set.
Step-by-step explanation:
The subject of this question is Computers and Technology. The grade level is High School. The StaticSet class is a generic class declaration in the StaticSet.java file. It uses a HashSet to implement a static set. The HashSet's contents are assigned at construction time and cannot be changed after.
The question pertains to a StaticSet generic class declaration which utilizes a HashSet to implement a set whose contents do not change after instantiation. In Java programming, static indicates that the set's contents are fixed upon construction and the set does not allow for modification post-creation. T
he StaticSet class is likely to have private member variables to store the elements and a constructor method where the HashSet is initialized with predefined values, ensuring immutability.
