How to sort two arraylists according to their size into a new arraylist <p>I have two objects each with an id and a list.I would like to have a third arraylist sorting this object according to the list size.and still have the correaponding id along with the list</p>

<ol>
<li><p>Create a <a href="http://java.sun.com/javase/6/docs/api/java/util/Comparator.html" rel="nofollow"><code>Comparator</code></a> which can compare two of the "id/list pairs" -- in this case, we compare the list sizes of the list component.</p></li>

How To Create a SQL Index to Improve ORDER BY performance <p>I have some SQL similar to the following, which joins four tables and then orders the results by the "status" column of the first:</p>
<pre><code>SELECT *
FROM a, b, c, d
WHERE b.aid=a.id AND c.id=a.cid AND a.did=d.id AND a.did='XXX'
ORDER BY a.status
<... | <p>I would say it's slow because the engine is doing scans all over the place instead of seeks. Did you mean to do SELECT a.* instead? That would be faster as well, SELECT * here is equivalent to a.*, b.*, c.*, d.*.</p>
<p>You will probably get better results if you put a separate index on each of these columns:</p>

Regular expression to transform 1.2.3 to 1.02.03 <p>i'm really not good with regular expressions and i need one to transform "1.2.3" to "1.02.03" in a way that first part stays always as it was and second and third one will transform 2 to 02, 7 to 07 and so on but if there is 10, 15, 17 and so on it will leave it as i... | <pre><code>/\.(\d)(?=\D|$)/g => .0$1
</code></pre>
<p>Works with any number of dots :)</p>
<p><strong>Edit:</strong> when look-ahead isn't supported but word boundaries are, you can use</p>
<pre><code>/\.(\d)\b/g => .0$1
</code></pre>
<p>... or just because it's simpler :)</p>

What makes Ruby slow? <p>Ruby is slow at certain things. But what parts of it are the most problematic?</p>
<p>How much does the garbage collector affect performance? I know I've had times when running the garbage collector alone took several seconds, especially when working with OpenGL libraries.</p>

<p>It does "late lookup" for methods, to allow for flexibility. This slows it down quite a bit. It also has to remember variable names per context to allow for eval, so its frames and method calls are slower. Also it la... |
Inheriting For Multiple Shapes - ASP.NET MVC <p>I'm returning multiple shapes to a page and am using a ViewData class that I've created. The namespace of this class is:</p>

</code></pre>
<p>You will then need to import that namespace for the ViewModel to be accessible on the ViewData.Model property within the view.</p>

Suppress backspace, delete keys in MaskedTextbox <p>The question is simple: how to do it?
I've a couple of MaskedTextboxes which are filled by some indirect user actions (so not by typing in values directly). The text within the textboxes is colored red when the input is being rejected by the mask. Fine so far.</p>
<p... | <p>I think it's a good idea to set the <code>MaskedTextBox</code>'s <code>ReadOnly</code> property to <code>true</code>. But instead of handling the <code>MaskInputRejected</code> event, you should use the <code>TypeValidationCompleted</code> event like this:</p>
