ArrayDeque class Methods in Java Part -I

java.util.ArrayDeque<E>

Resizable-array implementation of the Deque

interface. Array deques have no capacity restrictions; they grow as necessary to support usage. 

Some methods of ArrayDeque.

ArrayDeque.add(E): This method inserts the specified element at the end of this deque.

ArrayDeque.addAll(Collection): This method adds all of the elements in the specified collection at the end of this deque.

ArrayDeque.addFirst(E): This method inserts the specified element at the front of this deque.

ArrayDeque.addLast(E): This method inserts the specified element at the end of this deque.

ArrayDeque.clear(): The deque will be empty after this call returns.

ArrayDeque.clone(): This method returns a copy of this deque.

ArrayDeque.contains(Object): This method returns true if this deque contains the specified element.

AbstractCollection.containsAll(Collection): This method returns true if this collection contains all of the elements in the specified collection.

ArrayDeque.descendingIterator(): This method returns an iterator over the elements in this deque in reverse sequential order.

ArrayDeque.element(): This method retrieves but does not remove, the head of the queue represented by this deque.

Object.equals(Object): This method indicates whether some other object is "equal to" this one.

ArrayDeque.forEach(Consumer): This method performs the given action for each element of the Iterable until all elements have been processed or the action throws an exception.

ArrayDeque.getFirst(): This method retrieves but does not remove, the first element of this deque.

ArrayDeque.getLast(): This method retrieves but does not remove, the last element of this deque.

hashCode(): This method returns a hash code value for the object (ArrayDeque).

ArrayDeque.isEmpty(): This method returns true if this deque contains no elements.

ArrayDeque.offer(E): This method inserts the specified element at the end of this deque.

ArrayDeque.offerFirst(E): This method inserts the specified element at the front of this deque.

ArrayDeque.offerLast(E): This method inserts the specified element at the end of this deque.

parallelStream(): This method returns a possibly parallel Stream with this collection as its source.
