Map is an abstract data type that contains key-value pairs. In map, every key has to be unique. In java, HashMap and HashTable implement the Map interface.
Operations
put(key, value)Add a new key-value pair into the map. If the key is already exists in the map, the old value is replaced by the new.get(key)A key is passed as parameter, the corresponding value is returned.remove(key)A key is passed as parameter, the associate key-value pair is removed from the map.containsKey(key)Checks if the map contains a mapping for the specified key. Returns true if the map contains the key, otherwise returns false.containsValue(value)Checks if the map contains one or more keys mapping to the specified value. Returns true if the map contains at least one key-value pair with the specified value, otherwise returns false.
