    <p>From Javadoc:</p> <ul> <li>A <a href="http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ConcurrentLinkedQueue.html" rel="noreferrer">ConcurrentLinkedQueue</a> is an appropriate choice when many threads will share access to a common collection. This queue does not permit null elements.</li> <li><a href="http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ArrayBlockingQueue.html" rel="noreferrer">ArrayBlockingQueue</a> is a classic "bounded buffer", in which a fixed-sized array holds elements inserted by producers and extracted by consumers. This class supports an optional fairness policy for ordering waiting producer and consumer threads</li> <li><a href="http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/LinkedBlockingQueue.html" rel="noreferrer">LinkedBlockingQueue</a> typically have higher throughput than array-based queues but less predictable performance in most concurrent applications.</li> </ul> <p>I have 2 scenarios, one requires the queue to support many producers (threads using it) with one consumer and the other is the other way around.</p> <p>I am not understanding whether I should use <code>ConcurrentLikedQueue</code> or the other ones (the array or linkedList implementations). Wherent' all this implementations supposed to be concurrent? I mean, can somebody explain me what is the difference between <code>ConcurrentLikedQueue</code> and <code>LinkedBlockingQueue</code>?</p> <p>Also, what is the optional fairness policy thing in the <code>ArrayBlockingQueue</code> please?</p>

    1. COAre you sure this should be a community wiki? These questions sound like they have a definite answer. I could be wrong...

    3. CO@David: People can still edit your question even if it's not a community wiki. When a question is a community wiki, none of the people who answer will gain any reputation points (even if others up-vote the answers). Hopefully this clears things up for the future. :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
