Constructor

	LinkedList() Constructs an empty list.
	LinkedList(Collection c) Constructs a list containing the elements of the specified collection, in the order they are returned by the collection's iterator.

Method

void	add(int index, E element) Inserts the specified element at the specified position in this list.
boolean	addAll(Collection c) Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's iterator.
boolean	addAll(int index, Collection c) Inserts all of the elements in the specified collection into this list, starting at the specified position.
void	addFirst(E e) Inserts the specified element at the beginning of this list.
void	addLast(E e) Appends the specified element to the end of this list.
void	clear() Removes all of the elements from this list.
Object	clone() Returns a shallow copy of this LinkedList .
boolean	contains(Object o) Returns true if this list contains the specified element.
boolean	containsAll(Collection c) Returns true if this list contains all of the elements of the specified collection.
Iterator	descendingIterator()
E	element() Retrieves, but does not remove, the head (first element) of this list.
boolean	equals(Object o) Compares the specified object with this list for equality.
void	forEach(Consumer action) Performs the given action for each element of the Iterable until all elements have been processed or the action throws an exception.
E	get(int index) Returns the element at the specified position in this list.
E	getFirst() Returns the first element in this list.
E	getLast() Returns the last element in this list.
int	indexOf(Object o) Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.
boolean	isEmpty() Returns true if this list contains no elements.
Iterator	iterator() Returns an iterator over the elements in this list in proper sequence.
int	lastIndexOf(Object o) Returns the index of the last occurrence of the specified element in this list, or -1 if this list does not contain the element.
ListIterator	listIterator() Returns a list iterator over the elements in this list (in proper sequence).
ListIterator	listIterator(int index) Returns a list-iterator of the elements in this list (in proper sequence), starting at the specified position in the list.
boolean	offer(E e) Adds the specified element as the tail (last element) of this list.
boolean	offerFirst(E e) Inserts the specified element at the front of this list.
boolean	offerLast(E e) Inserts the specified element at the end of this list.
Stream	parallelStream() Returns a possibly parallel Stream with this collection as its source.
E	peek() Retrieves, but does not remove, the head (first element) of this list.
E	peekFirst() Retrieves, but does not remove, the first element of this list, or returns null if this list is empty.
E	peekLast() Retrieves, but does not remove, the last element of this list, or returns null if this list is empty.
E	poll() Retrieves and removes the head (first element) of this list.
E	pollFirst() Retrieves and removes the first element of this list, or returns null if this list is empty.
E	pollLast() Retrieves and removes the last element of this list, or returns null if this list is empty.
E	pop() Pops an element from the stack represented by this list.
void	push(E e) Pushes an element onto the stack represented by this list.
boolean	remove(Object o) Removes the first occurrence of the specified element from this list, if it is present.
E	remove(int index) Removes the element at the specified position in this list.
E	remove() Retrieves and removes the head (first element) of this list.
boolean	removeAll(Collection c) Removes from this list all of its elements that are contained in the specified collection (optional operation).
E	removeFirst() Removes and returns the first element from this list.
boolean	removeFirstOccurrence(Object o) Removes the first occurrence of the specified element in this list (when traversing the list from head to tail).
boolean	removeIf(Predicate filter) Removes all of the elements of this collection that satisfy the given predicate.
E	removeLast() Removes and returns the last element from this list.
boolean	retainAll(Collection c) Retains only the elements in this list that are contained in the specified collection (optional operation).
E	set(int index, E element) Replaces the element at the specified position in this list with the specified element.
void	sort(Comparator c) Sorts this list according to the order induced by the specified Comparator .
Stream	stream() Returns a sequential Stream with this collection as its source.
List	subList(int fromIndex, int toIndex) Returns a view of the portion of this list between the specified fromIndex , inclusive, and toIndex , exclusive.
T[]	toArray(T[] a) Returns an array containing all of the elements in this list in proper sequence (from first to last element); the runtime type of the returned array is that of the specified array.
Object[]	toArray() Returns an array containing all of the elements in this list in proper sequence (from first to last element).
String	toString() Returns a string representation of the object.
void	wait(long timeoutMillis) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
