title: Java Deque without using any of the existing classes like LinkedList?
body: <p>I've got to write a very short bit of code on a <code>deque</code>, however I'm not sure how to write the code for the methods, if someone could help me with one of the methods, (eg. a method to add an object to the from of the deque) then that would get me started. I'm sure I could manage the rest of the methods, just at the moment I'm pretty stumped.</p>
