     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"?
