Surely, you meant
java.util.HashSet<java.lang.Character> result
= new java.util.HashSet<java.lang.Character>();

Not a fair criticism, I'd say. "Hash" is not a specialization,
nor even a "thing" in its own right: It is merely a few characters
extracted from an identifier. In
class Settler<T> implements Set<T> {...}
Set<Character> result = new Settler<>();
... would it be in any sense useful to describe the LHS as being
derived from the RHS by the omission of "tler"?
