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.

Since:

4.0
