PrimitiveIterator.OfInt

AI-generated Key Takeaways

• PrimitiveIterator.OfInt is an iterator specifically designed for handling int values.

• It provides methods like nextInt() to directly retrieve the next int element and forEachRemaining() to process remaining elements.

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

• The forEachRemaining() method can accept both Consumer<Integer> and IntConsumer for processing elements.

• If there are no more elements to iterate, calling nextInt() will result in a NoSuchElementException.

public static interface PrimitiveIterator.OfInt implements PrimitiveIterator<Integer, IntConsumer>

An Iterator specialized for int values.

Public Method Summary

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

Inherited Method Summary

From interface java.util.PrimitiveIterator

abstract void

forEachRemaining(IntConsumer 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 Integer	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 Integer> action)

Parameters

action

public void forEachRemaining (IntConsumer 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 Integer next ()

Returns the next element in the iteration.

Returns

• the next element in the iteration

public abstract int nextInt ()

Returns the next int element in the iteration.

Returns

• the next int element in the iteration

Throws

NoSuchElementException	if the iteration has no more elements
