先看看JAVA API对ListIterator的说明: 需要注意的是nextIndex只是返回一个index,并没有修改其他的东西。而next取下一个index的元素不单单是取里面的元素,而且其游标(java没有指针,但这里的概念类似于指针)也会移动。在JAVA中有许多这样的情况发生。 打个比方,假如当前遍历的是序号为0的元素。当使用nextIndex()函数...
(1)ListIterator有add()方法,可以向List中添加对象,而Iterator不可以; (2)ListIterator和Iterator都有hasNext()和next()方法,可以实现顺序向后遍历,但是ListIterator有hasPrevious()和previous()方法,可以实现逆向(顺序向前)遍历。Iterator就不可以; (3)ListIterator可以定位当前的索引位置,nextIndex()和previousIndex()...

ListIterator是Java集合框架中的一个接口,它继承自Iterator接口,并在其基础上提供了更多的功能。通过ListIterator,我们可以在遍历列表时进行双向迭代,并且可以在遍历过程中进行修改、插入和删除操作。 ListIterator接口的定义如下: publicinterfaceListIterator<E>extendsIterator<E>{booleanhasNext();Enext();booleanhasPrevio...
