The HashMap Class implements the Map Interface of the java collection framework . The HashMap stores the element Key-Value pair in the hash table. HashMap does not provide synchronization but allows to provide “Null” Keys and “Null” Values . The HashMap uses initial capacity and load factor as parameters. The initial capacity determines the number […]
