The bucket id is hashvalue/buckets length. A hash map consists of buckets; objects will be placed in these buckets based on the bucket id. Any number of objects can actually fall into the same bucket based on their hash code / buckets length value.

WebJul 4, 2024 · When we put a value in the map, the key's hashCode() method is used to determine the bucket in which the value will be stored. To retrieve the value, HashMap calculates the bucket in the same way – using hashCode(). Then it iterates through the objects found in that bucket and use key's equals() method to find the exact match. 5.2. … WebWith modular hashing, the hash function is simply h(k) = k mod m for some m (usually, the number of buckets). The value k is an integer hash code generated from the key. If m is a power of two (i.e., m=2p ), then h(k) is just the p lowest-order bits of k. The SML/NJ implementation of hash tables does modular hashing with m equal to a power of two.

WebSep 6, 2024 · E.g. if we have initialized the HashTable with initial capacity of 16, then the hash function will make sure the key-value pairs will be distributed among 16 indexes equally, thus each bucket will carry as few elements as possible..
