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.

    Note that the return type is Object, rather than V as in the Map interface.

      Object put(K key, V value)
      Note that the return type is Object, rather than V as in the Map interface. See the class Javadoc for further info.
      key - key with which the specified value is to be associated
      value - value to be associated with the specified key
      the previous value associated with key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with key, if the implementation supports null values.)
