• • Method Detail

     * #### nextLong  
     long nextLong()  
     Returns the next `long` element in the iteration.  
     Returns:  
     the next `long` element in the iteration  
     Throws:  
     `[NoSuchElementException](../../java/util/NoSuchElementException.html "class in java.util")` \- if the iteration has no more elements  
     * #### forEachRemaining  
     default void forEachRemaining([LongConsumer](../../java/util/function/LongConsumer.html "interface in java.util.function") action)  
     Performs the given action for each remaining element until all elements have been processed or the action throws an exception. Actions are performed in the order of iteration, if that order is specified. Exceptions thrown by the action are relayed to the caller.  
     Specified by:  
     `[forEachRemaining](../../java/util/PrimitiveIterator.html#forEachRemaining-T%5FCONS-)` in interface `[PrimitiveIterator](../../java/util/PrimitiveIterator.html "interface in java.util")<[Long](../../java/lang/Long.html "class in java.lang"),[LongConsumer](../../java/util/function/LongConsumer.html "interface in java.util.function")>`  
     Implementation Requirements:  
     The default implementation behaves as if:  
     ```  
          while (hasNext())  
              action.accept(nextLong());  
            
     ```  
     Parameters:  
     `action` \- The action to be performed for each element  
     Throws:  
     `[NullPointerException](../../java/lang/NullPointerException.html "class in java.lang")` \- if the specified action is null  
     * #### next  
     default [Long](../../java/lang/Long.html "class in java.lang") next()  
     Returns the next element in the iteration.  
     Specified by:  
     `[next](../../java/util/Iterator.html#next--)` in interface `[Iterator](../../java/util/Iterator.html "interface in java.util")<[Long](../../java/lang/Long.html "class in java.lang")>`  
     Implementation Requirements:  
     The default implementation boxes the result of calling[nextLong()](../../java/util/PrimitiveIterator.OfLong.html#nextLong--), and returns that boxed result.  
     Returns:  
     the next element in the iteration  
     * #### forEachRemaining  
     default void forEachRemaining([Consumer](../../java/util/function/Consumer.html "interface in java.util.function")<? super [Long](../../java/lang/Long.html "class in java.lang")> action)  
     Performs the given action for each remaining element until all elements have been processed or the action throws an exception. Actions are performed in the order of iteration, if that order is specified. Exceptions thrown by the action are relayed to the caller.  
     Specified by:  
     `[forEachRemaining](../../java/util/Iterator.html#forEachRemaining-java.util.function.Consumer-)` in interface `[Iterator](../../java/util/Iterator.html "interface in java.util")<[Long](../../java/lang/Long.html "class in java.lang")>`  
     Implementation Requirements:  
     If the action is an instance of `LongConsumer` then it is cast to `LongConsumer` and passed to [forEachRemaining(java.util.function.LongConsumer)](../../java/util/PrimitiveIterator.OfLong.html#forEachRemaining-java.util.function.LongConsumer-); otherwise the action is adapted to an instance of`LongConsumer`, by boxing the argument of `LongConsumer`, and then passed to [forEachRemaining(java.util.function.LongConsumer)](../../java/util/PrimitiveIterator.OfLong.html#forEachRemaining-java.util.function.LongConsumer-).  
     Parameters:  
     `action` \- The action to be performed for each element
