Instantiating a queue class

[Logan 2]

Hello,
I know how to use a queue that enables simple to add or remove an item and retrieve the first element entered into it. I had to use that interface Tail java.util. But how can I instantiate the queue?

private Queue fileAttente = new ??();

This is what I want to know, If I am not wrong then this should be similar to something like this.

Hi,
In the javadoc, you list all classes that implement an interface that
All Known Implementing Classes:

AbstractQueue,
ArrayBlockingQueue,
ArrayDeque,
ConcurrentLinkedQueue,
DelayQueue,
LinkedBlockingDeque,
LinkedBlockingQueue,
LinkedList,
PriorityBlockingQueue,
PriorityQueue,
SynchronousQueue

If you need more information on this, you can visit the sun api documentation.

Hello,
If it is a linked list, it does not fit because I really want to implement a simple queue. It would suit me if it was a simple queue implemented using a linked list (adding lead does not interest me for example). What I want to do is to retrieve documents in a queue and handle them later on a FIFO (First In First Out). Suppose that several documents are saved in my queue. And although the first recorded being the first treaty etc. I hope to be clear. And in my case, what is the best implementation of the interface queue?

Hello,
I do not have an ideas how to do it in java, but in c++ it can be done some what like this

class testcl
{
    public:
            testcl(); // constructor
            // other methods
    private:
            std::priority_queue<orClass> queue;
};

As, I am a C++ programmer, i know the c++ method to do it, see if you get knowledge or some basic idea about how to do it.

Hello,
I thought that the methods push () and pop () was intended to batteries (LIFO) and not to queue (FIFO).
Also, when I do:

private Queue queue = <Document> new LinkedList <Document>();

I do not have the methods push () and pop () from my queue "queue".
I was wrong or is it you should read the Javadoc?

Hello,
A few days before even i was trying a program similar like this, that is a code to instantiate a queue object. I found it necessary to use a PriorityQueue, it implements a simple queue.

private Queue queue = <Document> new PriorityQueue <Document>();

This helped me for my coding, if you are interested then you can try the following. But i do not know for what purpose you are going to use it. Still, you can try it.
