“Deque” stands for “double-ended queue”; it’s supposed to be pronounced “deck”, but some people say “deek”. In Java, the Deque interface provides push, pop, peek, and isEmpty, so you can use a Deque as a stack.

it is easier to implement efficiently

If you limit yourself to a small set of methods — that is, a small API — your code will be more readable and less error-prone.

it is a collection that maintains the order of the elements. The primary difference between a stack and a list is that the stack provides fewer methods. In the usual convention, it provides:push: which adds an element to the top of the stack.pop: which removes and returns the top-most element from the stack.peek: which returns the top-most element without modifying the stack.isEmpty: which indicates whether the stack is empty.

Best Usecase scenario:- When our frequently used operation is adding or removing elements in the middle of the List, LinkedList is the best class to use.

Java LinkedList List Methods

We can use ListIterator to iterate LinkedList elements.

When we try to access an element from a LinkedList, searching that element starts from the beginning or end of the LinkedList based on where that elements is available.

It does not implement RandomAccess interface. So we can access elements in sequential order only.

the Omega notation defines whether the set of functions will grow faster or at the same rate as the expression
