What is LinkedList class?

What is LinkedList class?

- LinkedList class implements the List interface.

- In addition to the List operations, the LinkedList class supports the operations of inserting elements at the beginning and at the end of the list.

- The flexibility of these two methods allows LinkedList class to perform a stack, queue and double-ended queue operations.

public class LinkedList<E>
extends AbstractSequentialList<E>
implements List<E>, Deque<E>, Cloneable, Serializable

- Doubly-linked list implementation of the List and Deque interfaces.

- Implements all optional list operations, and permits all elements (including null).

- All of the operations perform as could be expected for a doubly-linked list. Operations that index into the list will traverse the list from the beginning or the end, whichever is closer to the specified index.
