Examples of java.util.Map.keySet()

java.util.Map.keySet()
Returns a {@link Set} view of the keys contained in this map.The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations. @return a set view of the keys contained in this map
