It provides the basic implementation of the this class makes no guarantees as to the order of the map. With this, we can give an unique identity to each such object and access any such object in a very quick time. Hashmap allows multiple null values but only one null key. Hashmap, as the name implies, groups the keys into buckets based on the keys' hashcode(). This class is found in java.util package.
It provides the basic implementation of the this class makes no guarantees as to the order of the map. Hashmap extends abstractmap and implements map. Hashmap in java in a collection class which implements map interface. Hashmap is actually a hash table moreover hashmap is unsynchronized compared to hashtable. There are several ways to iterate a hashmap in java.
