Doubly-linked lists, per Node, contain a pointer to the Node before the current Node, and the Node directly following. This is a lot of information to store, so it can sometimes be memory inefficient.
Compared to the Vector class, a list cannot be accessed through array notation (using square [4] brackets, with the number defining which Node to access). This means that a list must have an iterator to make it work and to make it editable.

Convert single linked list to double linked list?
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.
Does each node in a doubly linked list contain a link to the previous as well as the next node?
Yes, each node in a doubly linked list contain a link to the previous as well as the next node. That is the definition of the doubly linked list.
Which operation is perform more efficiently by doubly linked list than by single linked list?

What is difference between linked list and singly linked list?
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.
What is meant by doubly linked list?
In C programming, a double linked-list refers to a linked data structure that contains a set of links that have been linked sequentially.
