Method Details

nextInt
int nextInt()Returns the nextint
element in the iteration.- Returns:
- the next
int
element in the iteration - Throws:
NoSuchElementException
- if the iteration has no more elements
-
forEachRemaining
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.The behavior of an iterator is unspecified if the action modifies the source of elements in any way (even by calling the
remove
method or other mutator methods ofIterator
subtypes), unless an overriding class has specified a concurrent modification policy.Subsequent behavior of an iterator is unspecified if the action throws an exception.
- Specified by:
forEachRemaining
in interfacePrimitiveIterator<Integer,
IntConsumer> - Implementation Requirements:
The default implementation behaves as if:
while (hasNext()) action.accept(nextInt());
- Parameters:
action
- The action to be performed for each element
-
next
-
forEachRemaining
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.The behavior of an iterator is unspecified if the action modifies the collection in any way (even by calling the
remove
method or other mutator methods ofIterator
subtypes), unless an overriding class has specified a concurrent modification policy.Subsequent behavior of an iterator is unspecified if the action throws an exception.
- Specified by:
forEachRemaining
in interfaceIterator<Integer>
- Implementation Requirements:
- If the action is an instance of
IntConsumer
then it is cast toIntConsumer
and passed toforEachRemaining(java.util.function.IntConsumer)
; otherwise the action is adapted to an instance ofIntConsumer
, by boxing the argument ofIntConsumer
, and then passed toforEachRemaining(java.util.function.IntConsumer)
. - Parameters:
action
- The action to be performed for each element
