Collaboration diagram for ArrayIterator:

Static Public Member Functions
static< E > Iterator< E >	iterator (final E[] array)

static void	main (final String[] args)

Protected Member Functions
	ArrayIterator ()

Detailed Description

The code sample illustrates the usage of default methods in the JDK 8. Most implementations of Iterator don't provide a useful Iterator#remove() method, however, they still have to implement this method to throw an UnsupportedOperationException. With the default method, the same default behavior in interface Iterator itself can be provided.

Constructor & Destructor Documentation

◆ ArrayIterator()

ArrayIterator.ArrayIterator ( )

protected

Close the constructor because ArrayIterator is part of the utility class.

Member Function Documentation

◆ iterator()

static <E> Iterator<E> ArrayIterator.iterator ( final E[] array )

static

Returns an iterator that goes over the elements in the array.

Parameters

<E>	type of an array element
array	source array to iterate over it

Returns: an iterator that goes over the elements in the array

Index of the current position

Returns the next element in the iteration

Returns: the next element in the iteration

Exceptions

NoSuchElementException if the iteration has no more elements

Returns

true

if the iteration has more elements. (In other words, returns

true

if next returns an element, rather than throwing an exception.)

Returns: true

if the iteration has more elements

This method does not need to be overwritten in JDK 8.
