a) Hashing: When you insert a key-value pair, the HashMap applies the hashCode() method on the key to generate a hash value. This hash value is then used to determine the index of the corresponding bucket in the underlying array.b) Handling Collisions: In some cases, different keys can...
A Multimap is a map that allows a single key to be mapped to multiple values. Because theJDKdoes not include an implementation of the Multimap, programmers frequently overlook it in Java.
