Detailed introduction to power nodes

Iterator is a pattern that can separate the traversal behavior of sequence type data structures from the traversed objects. Next, I will share with you the Java Iterator through this article_Compiled by Power Node Java Academy, friends in need For reference, iterator is a pattern that can separate the traversal behavior of a sequence type data structure from the object being traversed, that is, we do not need to care about what the underlying structure of the sequence looks like. As long as you get this object, you can use an iterator to traverse the interior of this object. 1. IteratorJava provides a specialized iterator <>Iterator. We can implement this interface for a certain sequence to provide standard Java iterator. The function after the Iterator interface is implemented is to "use" an iterator. Document definition: Package java.util; publicinterface Iterator { boolean&am
