HashCode() and equals()

Although they may produce the same or similar results in some cases, they are not the same. They do however have a tight bond and are relational. The hashCode() method represents the identity of the current instance of an object, while the equals() method typically represents the equality between 2 object instances where the hashCode may be used for comparison.
