In this section, we will discuss some of the important points about Java LinkedList: Java LinkedList class is a member of the Java Collections Framework. It is an implementation of the List and Deque interfaces. Internally, it is an implemented using Doubly Linked List Data Structure. It supports duplicate elements. It stores or maintains it’s elements in Insertion order. We can add any number of null elements.
