Hashmap internally maintain buckets of elements. Whenever an element with key is searched for inside hashmap it calculates the hashcode for the key to be searched. Based on the hashcode it selects the right bucket for it. So multiple element key values may point to the same bucket so again all the elements are maintained in a linked list form inside each bucket. Now each node in that linked list contains both the key and value. So whenever a particular key is searched for it traverses that linked list in the corresponding bucket and returns the matching value for the key.
