e342. Implementing a Queue

    LinkedList queue = new LinkedList();
    
    // Add to end of queue
    queue.add(object);
    
    // Get head of queue
    Object o = queue.removeFirst();
    
    // If the queue is to be used by multiple threads,
    // the queue must be wrapped with code to synchronize the methods
    queue = (LinkedList)Collections.synchronizedList(queue);
