It provide a linked-list data structure.get free coins thetechieking --  It inherits the AbstractList class and implements List and Deque interfaces in java. --  LinkedList class is non synchronized. --  LinkedList class follow insertion order.  --  LinkedList class can allow duplicate elements to store data. --  manipulation is faster than ArrayList because no shifting needs. Declaration of LinkedList class in java : -- public class LinkedList<E> extends AbstractSequentialList<E>    implements List<E>, Deque<E>, Cloneable, Serializable   Constructors of Java LinkedList :  LinkedList()   LinkedList(Collection c) Methods of LinkedList class : 1) boolean add ( Object element ) : -- It appends the element to the end of the list. 2) void add ( int index, Object element ) : -- It inserts the element at the position
