in Java  Implement an Array-Based of the ADT Queue and verify "isEmpty()",  "enqueue()", "dequeue()", "dequeueAll()", and "peak()" operations.

implement code of  the Queue ADT with a linked list

Define the abstract base class LinkedSQD_Base using a linked implementation. Indicate whether each field and method should be public, protected, or private, and explain why. Implement each of the ADTs stack, queue, and deque as a class that extends your base class. Repeat parts a and b, but instead define and use the abstract base class ArraySQD_Base using an array-based implementation. Java program

The circular array queue implementation increased the dequeue operation's performance from O(n) to O(1) by doing away with the requirement to move array items. Adding or removing members from a list can occur anywhere along its length, not simply at the front or back, thus this is not true.
