01. Internal Working of HashMap & Java-8 Enhancement

[@evgenii550]

you said that the capacity will be increased if 12 buckets will be full (for initial capacity = 16), but if i try to use class, which hashCode() always returns 1, as a key, then all the new pairs will be stored in one bucket with index 1 and according to debugging the capacity will still be increased. doesn't this mean that the load factor depends on the number of pairs in the hash map? not on the number of buckets with pairs

[@ankit.wasankar]

ah good catch, let me pin 📌 this post. thanks for your comment.

[@cyberulitka4661]

thank you for your comment! good point!

[@ukj6795]

nice observation, thanks for sharing this

[@dhanashreekamali3185]

Is loadfactor depending on number of entries in Hashmap? @webencyclop (if not what is the meaning of pairs here? what does this pair signify?)

[@pratikbhange2757]

[@monikapreethi4847]

thankyou so much. its really excellent explanation with neat slides, think your the best tutor to explain the concept in a simplified manner. I think its the best video on hash map .

[@AkhileshKumar-li6me]

Kindly note that when hashmap is passed the duplicate key, it calls the hashCode() method to generate the hash value for the key and this hash value helps in determining where to put this new entry but since this index/position already has one entry. Since each bucket stores the entry/ies in the form of a linked list so new entry will be added at the top/right end of the linked list. The same logic will be applied if another duplicate key arrives. Please note, when we try to retrieve the value by passing the key(which is duplicate in nature), hashmap goes to the appropriate index by calculating the hash value and traverses the linked list, and returns the most recent value as all the keys are same.
