 Classes to support functional-style operations on streams of elements, such
 as map-reduce transformations on collections. 
 | 
| javax.management.openmbean | 
 Provides the open data types and Open MBean descriptor classes.

| Modifier and Type | Method and Description | 
|---|---|
default void | 
Spliterator.OfDouble.forEachRemaining(Consumer<? super Double> action)
Performs the given action for each remaining element, sequentially in
 the current thread, until all elements have been processed or the action
 throws an exception. 
 | 
default void | 
PrimitiveIterator.OfDouble.forEachRemaining(Consumer<? super Double> action)

 have been processed or the action throws an exception. 
 | 
default boolean | 
Spliterator.OfDouble.tryAdvance(Consumer<? super Double> action)
If a remaining element exists, performs the given action on it,
 returning  
true; else returns false. |
