Method Details
-
nextDouble
double nextDouble()Returns the nextdoubleelement in the iteration.- Returns:
- the next
doubleelement 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
removemethod or other mutator methods ofIteratorsubtypes), 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:
forEachRemainingin interfacePrimitiveIterator<Double,DoubleConsumer> - Implementation Requirements:
The default implementation behaves as if:
while (hasNext()) action.accept(nextDouble());- Parameters:
action- The action to be performed for each element
-
next
Returns the next element in the iteration.- Specified by:
nextin interfaceIterator<Double>- Implementation Requirements:
- The default implementation boxes the result of calling
nextDouble(), and returns that boxed result. - Returns:
- the next element in the iteration
-
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
removemethod or other mutator methods ofIteratorsubtypes), 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:
forEachRemainingin interfaceIterator<Double>- Implementation Requirements:
- If the action is an instance of
DoubleConsumerthen it is cast toDoubleConsumerand passed toforEachRemaining(java.util.function.DoubleConsumer); otherwise the action is adapted to an instance ofDoubleConsumer, by boxing the argument ofDoubleConsumer, and then passed toforEachRemaining(java.util.function.DoubleConsumer). - Parameters:
action- The action to be performed for each element
