You must override hashCode in every class that overrides equals(). Equal objects must have equal hash codes. In other words, If two objects are equal according to the equals (Object)method, then calling the hashCode method on each of the two objects must produce the same integer result. Overriding equals() method states the criteria for object equality and overriding hashCode() makes sure that Once two objects are equal, they always return the same hash code value.
