![]() It is used to compare the specified Object with the Map. This method returns true if some key equal to the key exists within the map, else return false. This method returns true if some value equal to the value exists within the map, else return false. It is used to compute a new mapping given the key and its current mapped value if the value for the specified key is present and non-null. V computeIfPresent(K key, BiFunction remappingFunction) It is used to compute its value using the given mapping function, if the specified key is not already associated with a value (or is mapped to null), and enters it into this map unless null. V computeIfAbsent(K key, Function mappingFunction) It is used to compute a mapping for the specified key and its current mapped value (or null if there is no current mapping). V compute(K key, BiFunction remappingFunction) It removes the specified values with the associated specified keys from the map. It is used to delete an entry for the specified key. It inserts the specified value with the specified key in the map only if it is not already specified. It is used to insert the specified map in the map. It is used to insert an entry in the map. ![]() It is used to return a set view of the keys contained in this map. It is used to return a collection view of the mappings contained in this map. It is used to return a shallow copy of this HashMap instance: the keys and values themselves are not cloned. It is used to return true if this map contains no key-value mappings. It is used to remove all of the mappings from this map. It is used to initialize both the capacity and load factor of the hash map by using its arguments. It is used to initializes the capacity of the hash map to the given integer value, capacity. It is used to initialize the hash map by using the elements of the given Map object m. It is used to construct a default HashMap.
