Override equals() in Java In Java, Overriding is when the child class or the subclass has the same execution of method as declared in the parent class . The equals() method compares two strings. If the data of one string object is the same as the other, it returns True value otherwise False.19 Haz 2021

As a side note, when we override equals(), it is recommended to also override the hashCode() method . If we don’t do so, equal objects may get different hash-values; and hash based collections, including HashMap, HashSet, and Hashtable do not work properly (see this for more details).29 Tem 2021

if you override equals, you must override hashCode. hashCode must generate equal values for equal objects. equals and hashCode must depend on the same set of significant fields . You must use the same set of fields in both of these methods .31 Ara 2021
