Your attributions are messed up. You quote two people, but only attribute one.

First answer how these terms are "ordinarily understood", according to you. "Distinct" does not mean "not equal". "Distinct" means "not identical". "Equal" means "have the same value". Things can be distinct and equal, as Patricia has pointed out several times now. Java embodies this distinction by having both the operator == and the method 'equals()'. Distinct objects can be equal. For two references 'a' and 'b', both 'a != b' and 'a.equals( b )' can be true at once. So to answer your question, Laramie, 'equals()' applies to the concept of "equal" as ordinarily understood; '==' applies to "distinct" as ordinarily understood; 'hashCode()' applies to both "equal" and "distinct" as ordinarily understood; and 'System.identityHashCode()' has to do with "distinct" as ordinarily understood.
