Answer 1

Have you intentionally defined equality as when ids are equal OR names are equal.. Shouldnt the "OR" be a "AND" ?

If you meant "AND" then your hashcode should be calculated using the very same or less (but never use fields not used by equals) fields you are by equals().

If you meant "OR" then you r hashgcode should not include id or name in its hashcode calculation which doesnt really make sense.
