One question
Should we override both hashcode and equals method while working hashmap Or hashset
To eliminate duplicate objects adding to set

What happened if we only override equals method
Will set or map will allow duplicate

Plz reply
Thanks in advance

what the use of overriding hashcode here? It looked like equals() alone is sufficient to differentiate between two objects.
