PrimitiveIterator.OfDouble

AI-generated Key Takeaways

• PrimitiveIterator.OfDouble is a specialized iterator for handling double values in Java.

• It provides methods like nextDouble() to directly access primitive double elements, and forEachRemaining() to process remaining elements with a DoubleConsumer or Consumer<Double>.

• This iterator inherits functionalities from PrimitiveIterator and Iterator, offering methods such as hasNext(), next(), and remove().

• nextDouble() throws a NoSuchElementException if there are no more elements, while forEachRemaining() throws a NullPointerException if the provided action is null.

public static interface PrimitiveIterator.OfDouble implements PrimitiveIterator<Double, DoubleConsumer>

An Iterator specialized for double values.

Public Method Summary

void	forEachRemaining(Consumer<? super Double> action)
void	forEachRemaining(DoubleConsumer action) Performs the given action for each remaining element until all elements have been processed or the action throws an exception.
Double	next() Returns the next element in the iteration.
abstract double	nextDouble() Returns the next double element in the iteration.

Inherited Method Summary

From interface java.util.PrimitiveIterator

abstract void

forEachRemaining(DoubleConsumer action) Performs the given action for each remaining element, in the order elements occur when iterating, until all elements have been processed or the action throws an exception.

From interface java.util.Iterator

void	forEachRemaining(Consumer<? super E> action) Performs the given action for each remaining element until all elements have been processed or the action throws an exception.
abstract boolean	hasNext() Returns true if the iteration has more elements.
abstract Double	next() Returns the next element in the iteration.
void	remove() Removes from the underlying collection the last element returned by this iterator (optional operation).

Public Methods

public void forEachRemaining (Consumer<? super Double> action)

Parameters

action

public void forEachRemaining (DoubleConsumer 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.

Parameters

action	The action to be performed for each element

Throws

NullPointerException	if the specified action is null

public Double next ()

Returns the next element in the iteration.

Returns

• the next element in the iteration

public abstract double nextDouble ()

Returns the next double element in the iteration.

Returns

• the next double element in the iteration

Throws

NoSuchElementException	if the iteration has no more elements
