If you use the second version, you probably also want to call super(equals()) inside your equals() method. Opinions differ here, the topic is discussed in this question: right way to incorporate superclass into a Guava Objects.hashcode() implementation? (although it's about hashCode(), the...

I'm not sure how to correctly implement hashCode() so that the hashCode would be equal if it satisfies the conditions of the equals() method. I would really appreciate your input! Thanks! public class Test { private double value; private boolean isEqualValues (final dou...
