    <p>1) They have to be <code>static</code>, in order to not be overridden in some sub class. I hope you understand.</p> <p><strong><code>&lt;Addendum&gt;</code></strong></p> <p>Shrini, from your comment, it seems that there is a need to explain the things to avoid some misconceptions. First of all, know on thing that <code>static</code> methods can not be overridden. Overriding is exclusive in objects, and it is there to facilitate polymorphism. Whereas static methods belongs to the class. Found a couple of good resources to support my argument and for you to understand that static methods can not be overridden.</p> <ul> <li><a href="http://geekexplains.blogspot.com/2008/06/can-you-override-static-methods-in-java.html" rel="nofollow noreferrer">Can you override static methods in Java</a></li> <li><a href="http://forums.sun.com/thread.jspa?threadID=597378" rel="nofollow noreferrer">Why static methods can't be abstract</a></li> </ul> <p>Now for your second retort, you are right in saying that they have package level access and can't be overridden in subclasses outside the package. But I don't know why are you neglecting the case where subclass/es exist in the same package. Its a valid case, IMO. In fact, it would be absurd to name a method like <code>access$000()</code> or something like that, in a real work. But don't underestimate the chance of accidental overriding. There can be a case where the subclass of <code>Outer</code>, say <code>SubOuter</code>, has an inner class of itself too. I didn't try to <code>javap</code> that case myself, just guessing.</p> <p><strong><code>&lt;/Addendum&gt;</code></strong></p> <p>2) Even if you think it will not get modified, technically there is a possibility as cletus pointed out already, use of <code>final</code> can provide easy optimizations by the compiler.</p>

    1. COHi Vinegar, thanks for your answer. But subclasses can override their parent classes' static methods; plus in this specific case the methods are package access, so subclasses outside of this package won't be able to override them anyway. So I don't understand #1 of your answer.

    3. COHi Vinegar, thank you for your explanation. I had coded a super/sub class and tested it before making my earlier reply; but I hadn't considered the case where a superclass ref points to a subclassed object. Thanks for pointing that out. And my apologies if my reply offended you; that was never the intention.

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.
