3Considering you hardly have a reason to use `java.util.LinkedList`... basically never. – Andy Turner Feb 17 '18 at 18:36

2Because otherwise you fail the class. Can't think of any other reason. – Elliott Frisch Feb 17 '18 at 18:37

A developer may hope to improve [some of the properties](https://stackoverflow.com/questions/322715/when-to-use-linkedlist-over-arraylist/322742#322742) of `LinkedList`. – lexicore Feb 17 '18 at 19:39

LinkedList implementation in Java is a Doubly-linked list. So it will take more memory space than Singly linked list. So, if your application is too much memory critical then you can think to implement a Singly linked list implementation. However, some operation in a Doubly-linked list is faster than a single linked list, you need to keep in mind the performance aspect also.
