put
V put(K key, V value)
Associates the specified value with the specified key in this map (optional operation). If the map
previouslycontained a mapping for the key, the old value is replaced by the specified value. (Amap
m is said to contain amapping for a key k if and only if m.containsKey(k) would return true.)
Parameters:
key – key with which the specified value is to be associated
value – value to be associated with the specified key
Returnsthe previous value associated with key, or null if there was no mapping for key. (A null
return can alsoindicate that the map previously associated null with key, if the implementation
supports null values.)
