| Package | Description | 
|---|---|
| java.util | Contains the collections framework, legacy collection classes, event model,
date and time facilities, internationalization, and miscellaneous utility
classes (a string tokenizer, a random-number generator, and a bit array). | 
| java.util.function | Functional interfaces provide target types for lambda expressions
 and method references. | 
| java.util.stream | Classes to support functional-style operations on streams of elements, such
 as map-reduce transformations on collections. |

| class  | LongSummaryStatisticsA state object for collecting statistics such as count, min, max, sum, and
 average. | 
| Modifier and Type | Method and Description | 
|---|---|
| default void | Spliterator.OfLong. forEachRemaining(LongConsumer action) | 
| default void | PrimitiveIterator.OfLong. forEachRemaining(LongConsumer action)Performs the given action for each remaining element until all elements
 have been processed or the action throws an exception. | 
| void | OptionalLong. ifPresent(LongConsumer consumer)Have the specified consumer accept the value if a value is present,
 otherwise do nothing. | 
| boolean | Spliterator.OfLong. tryAdvance(LongConsumer action) |

| void | LongStream. forEach(LongConsumer action)Performs an action for each element of this stream. | 
| void | LongStream. forEachOrdered(LongConsumer action)Performs an action for each element of this stream, guaranteeing that
 each element is processed in encounter order for streams that have a
 defined encounter order. | 
| LongStream | LongStream. peek(LongConsumer action)Returns a stream consisting of the elements of this stream, additionally
 performing the provided action on each element as elements are consumed
 from the resulting stream. |
