Interface declaring equals(Object)?

I can't find a standard API interface which just declares equals(Object) and
hashCode(), which are the minimum implementation for any object used as a
key in a map. Have I missed something? Wouldn't this be a useful thing to
have?

I ask because I just made what must be a classic beginner's mistake of
defining equals(SomeClass x) in SomeClass, instead of equals(Object x). :/
