Package org.aoju.bus.core.collection

Class ArrayIterator<E>

java.lang.Object

org.aoju.bus.core.collection.ArrayIterator<E>

Type Parameters:

E - 元素类型

All Implemented Interfaces:

Serializable, Iterable<E>, Iterator<E>, IterableIterator<E>, ResettableIterator<E>

public class ArrayIterator<E>
extends Object
implements IterableIterator<E>, ResettableIterator<E>, Serializable

实现一个Iterator 任何数组的迭代器 数组可以是对象数组,也可以是基元数组 如果你知道 class是更好的选择,因为它会表现得更好 迭代器实现了一个reset()方法,允许重置 如果需要,迭代器返回到开始

Since:

Java 17+
