I need the answer as soon as possible

Extracted text: Provide pseudocode or Java for an instance method to be added to the ArrayQueue class called demote, that takes a parameter E e and moves said element to the back of the ArrayQueue if it exists. You may assume the elements are unique and Comparable. For example, if your ArrayQueue logically contained "[4, 8, 15, 16, 23, 42]" before demote(new Long (16L)), it should logically contain "[4, 8, 15, 23, 42, 16]" after. Throw a NoSuchElementException if the ArrayQueue is empty or e is not in the ArrayQueue and an IllegalIArgumentException if e is null .
