A LinkedList is an implementation of the List interface. It is a collection that is ordered by index position, and the elements are doubly-linked to one another. The linking allows for addition and removal of elements from beginning or end. This class, as of Java 5, also implements the java.util.Queue interface.
I'm sorry brother
You copy a singly linked list into a doubly linked list by iterating over the singly linked list and, for each element, calling the doubly linked list insert function.
Basically, A linked list that has its tail linked to its head, usually the tail is kept track of since it provides constant access to both the end and the front of the linked list. ListNode x = new ListNode( value, null); //a ListNode with no next x.setNext( new ListNode( value, null)); // make its next another ListNode with no next x.getNext().setNext(x); // set the new node's next to my old node, now you have a circular linked list.
It is easier to insert into a singly linked list.
A list is an abstract data structure, usually defined as an ordered collection of data. A linked list refers to a specific implementation of a list in which each element in the list is connected (linked) to the next element.
Java's List interface defines the size() method, which can be used to retrieve the length of a list.
Linked list of strings, for example.

A doubly linked list is a linked list in which each node knows where both of its neighbors are.A circular linked list is a linked list in which the "tail" of the list is linked to the "root". (Note that both the tail and root of the list are undefined/arbitrary in a circular linked list)Doubly linked lists are actually not necessarily related to circular linked list (aside from both being based on a linked list structure). In fact, you can have a circular doubly linked list, where each node knows where both of its neighbors are andwhere the list wraps around to connect to itself.
Answersingly linked list has the node inserted only at one end. and the pointer corresponds to the next pointer.but in a doubly linked list, the node pointer points to the both previous and the next node.singly linked list has two nodesdoubly linked list has three nodesA doubly linked list makes sense when you need to traverse the list in both directions. You aren't able to do that with a singly linked list.
linked list are used for creation of stack,queues to use memory in optimum manner linked list are used as they are dynamic in nature
