Word problem...PROBLEM!

Hi guys!... im having a hard time analyzing about this word problem that was given to me, can anyone help me or atleast give an idea on how to solve this?...

Word Problem---
A queue is a list that is used in a restricted way. Items are always added to the end of the list. For example, when X is added to A, B, C, the result is A, B, C, X. items can only be removed from the front of the list. In order to remove C from the list, A and B must first be removed. Write a set of methods for treating an array of character of characters as queue. It should include method for insertion and deletion. The limits of the arrays index should be defined constants of type integer.

Have you started to write any code yet?

Please show us what you have and we can help you move forward..

I would recommend using a doubly linked list. You'll need to keep track of the head/tail nodes, but you'll only need to concern yourself with adding a node at the tail and removing nodes from the head (or vise-versa). Using an array would work too, but I think is a little bit counter-intuitive and inefficient.

If you're unsure on how to program in Java, I'd suggest reading Trail: Learning the Java Language (The Java™ Tutorials).
