listIterator(); } public abstract ListIterator listIterator(int index);} This class uses a large number of Iterator for sequential traversal of sets. Because it cannot be randomly located, this class focuses on sequential traversal. If you want to implement a list set by yourself, it is best to inherit this abstract class, in this way, you don't have to bother yourself to implement so many methods. Struct List is a reality of sub-structure Li
