In Java, ListIterator is an interface in Collection API. It extends Iterator interface. To support Forward and Backward Direction iteration and CRUD operations, it has the following methods. We can use this Iterator for all List implemented classes like ArrayList, CopyOnWriteArrayList, LinkedList, Sta...
next in interface Iterator<E> Returns: the next element in the list Throws: NoSuchElementException - if the iteration has no next element hasPrevious boolean hasPrevious() Returns true if this list iterator has more elements when traversing the list in the reverse direction. (In other words, ...
3. Java Iterator for Simple Iteration To overcome some of the above disadvantages of theEnumeration, Java introduced thejava.util.Iteratorinterface in JDK1.2.Iteratorcan be used to iterate over the elements of any collection classes present in Java, hence it is a universal cursor. Iterating using...

#JavaList反向迭代的全面探讨 在Java编程中,集合框架(Collection Framework)提供了多种数据结构与算法来处理数据。List是Java中一组重要的数据结构,特别适合存储有序的元素。当我们需要反向访问List中的元素时,反向迭代(Reverse Iteration)显得尤为重要。本文将详细介绍JavaList的反向迭代,包括其实现方式和实际应用 ...
Returns an unmodifiable List containing the elements of the given Collection, in its iteration order. boolean equals(Object o) Compares the specified object with this list for equality. E get(int index) Returns the element at the specified position in this list. int hashCode() Returns the hash...
