Answer to Question #328096 in Java | JSP | JSF for Hussain

Question

You should create two methods for a data structure implementing a Queue as a

circular array. Your data structure should have the class name MyArrayQueue. The

two methods that should be implemented are:

a) Adding element to the queue:

public void enqueue(Object theElement) {…}

b) Deleting an element from the queue and return the deleted element:

public Object dequeue() {…}

[10 marks]

(Functionality: 6, Design: 2, Ease of use: 1, Presentation: 1)

In both methods errors should be handled properly. For example what happens

when adding an element to a full queue?

There will be skeleton code for MyArrayQueue available on Learning central that

contains the MyArrayQueue class with the following fully implemented methods:

constructor, isEmpty(), getFrontElement(), getRearElement() methods. It also

includes signatures of two methods that you should implement: enqueue(Object

theElement) & dequeue().
