public interface Put<K,V> 
The "write" subset of the 
Map interface.
 
 NOTE: in the original Map interface, Map.put(Object, Object) is known
 to have the same return type as Map.get(Object), namely V. Put
 makes no assumptions in this regard (there is no association with, nor even knowledge
 of, a "reading" interface) and thus defines put(Object, Object) as returning
 Object.

Method Details-

putAssociates the specified value with the specified key in this map.Note that the return type is Object, rather than V as in the Map interface. See the class Javadoc for further info. - Parameters:
- key- key with which the specified value is to be associated
- value- value to be associated with the specified key
- Returns:
- the previous value associated with key, ornullif there was no mapping forkey. (Anullreturn can also indicate that the map previously associatednullwithkey, if the implementation supportsnullvalues.)
