迭代器和Listiterator的区别?

2022-01-10 00:00:00 list set iterator java listiterator
Iterator ite = Set.iterator();
Iterator ite = List.iterator();

ListIterator listite = List.listIterator();

我们可以使用Iterator 来遍历SetListMap.但是ListIterator只能用来遍历List,不能遍历Set.为什么?

We can use Iterator to traverse a Set or a List or a Map. But ListIterator can only be used to traverse a List, it can't traverse a Set. Why?

我知道主要区别在于,使用迭代器我们只能在一个方向上移动,而使用 ListIterator 我们可以双向移动.还有其他区别吗?ListIteratorIterator 有什么优势?

I know that the main difference is that with iterator we can travel in only one direction but with ListIterator we can travel both directions. Are there any other differences? And any advantages of ListIterator over Iterator?

推荐答案

ListIterator

你可以

  • 向后迭代
  • 随时获取迭代器.
  • 随时添加新值.
  • 此时设置一个新值.
