<hr>
<p>According to the definition, every non-static method in Java is by default <strong>virtual method</strong> except <strong>final and private methods</strong>. The method which cannot be inherited for <strong>polymorphic</strong> behavior is <strong>not</strong> a virtual method.</p>

<p>Why do we say that a static method in Java is not a virtual method? Even if we can override the static method and consequently it may give some advantages of the <strong>polymorphism</strong> and also a static method in Java can be invoked mostly with it's associated class name but it is also possible to invoke it using the object of it's associated class in <strong>Java</strong> in the same way that an instance method is invoked.</p>

<p>1) How much exactly is revenue per impression and per click?</p>
<p>2) I have not seen ads showing up on my own device, but they do show up on my friends' devices. Is it supposed to be like this?</p>
<p>3) What if someone clicks on different ads multiple times on the same device, say, throughout the day? Is it still the same amount of revenue per click? or does it count as once since it is on the same device? If it is allowed, wouldn't that be a source of sort of an intentional multi-clicking just for sake of revenues?</p>
<p>4) How frequently are the revenues deposited to your account?</p>
<p>5) Does click-through rate increase just by clicking the ad, or actually installing it?</p>
<p>that's about it.
Please clarify these issues for me!

<p>When the user clicks on any input in the form, it is focussed. When a user clicks out of the form from any input it is blurred, but, the blur does not get triggered between tabbing between inputs in the form itself.</p>
<p>For something like this, we're looking at this basic structure:</p>
<pre><code><form>
<input ... />
<input ... />
<input ... />
</form>

<p>So again, lets say I click on any input in the form, we know the form is focused. Next, when the user clicks off of ANY input the blur is triggered ONLY if we clicked outside the form.</p>
<p>I've asked this question previously and kindly received input on how to achieve the blurring effect when the last input field in the form was blurred, but not from any element in the input list.</p>

The data is wiped out as soon as you send the form to the server so to get back the data, a session should be use. I have a dropdown that is a list of country. It contains more than 60-80 countries. I used the ternary condition to make the script shorter but it's still very long and tiresome.</p>
<p>It looks like this</p>
<pre><code><option value="Afghanistan" <?php echo (isset($_SESSION["errors"]) && $_SESSION["country"] == "Afghanistan") ? "SELECTED" : ""; ?> >Afghanistan</option>
<option value="Albania" <?php echo (isset($_SESSION["errors"]) && $_SESSION["country"] == "Albania") ? "SELECTED" : ""; ?>>Albania</option>

<p>I have a card game app I'm working on. When I flip the android device, switching from landscape to portrait (or vice verse), my card game starts from the beginning. </p>
<p>Every time the android device gets flipped, it calls the create method. I'm assuming it is creating a new intent? Is their anyway to stop this? Can it keeps the same intent if the device is flipped?</p>

4,495,305 | 4,495,306 | Private variables in inherited prototypes | <p>I think I have misunderstood how Javascript prototypal inheritance works. Specifically, the prototypes internal variables seem to be shared between multiple different sub-objects. It is easiest to illustrate with code:</p>
<pre><code>var A = function()
{
var internal = 0;
this.Increment = function()
{
return ++internal;
};
};
var B = function() {};
// inherit from A
B.prototype = new A;
x = new B;
y = new B;
$('#hello').text(x.Increment() + " - " + y.Increment());
</code></pre>
<p>This outputs <code>1 - 2</code> (test it on <a href="http://jsbin.com/ateci3/2/edit">JSBin</a>), while I fully expected the result to be <code>1 - 1</code>, since I wanted two separate objects.</p>
<p>How can I make sure that the <code>A</code> object isn't shared object between multiple instances of <code>B</code>?</p>
<p><strong>Update</strong>: <a href="http://robertnyman.com/2008/10/21/javascript-inheritance-experimenting-with-syntax-alternatives-and-private-variables/">This article</a> highlights some of the issues:</p>
<blockquote>
<p>The problem is that the scope each approach uses to create a private variable, which works fine, is also the closure, in action, that results in if you change a private variable for one object instance, it is being changed for all. I.e. it’s more like a private static property, than an actual private variable.</p>
<p>So, if you want to have something private, more like a non-public constant, any of the above approaches is good, but not for actual private variables. Private variables only work really well with singleton objects in JavaScript.</p>
</blockquote>
<p><strong>Solution</strong>: As per BGerrissen's answer, changing the declaration of <code>B</code> and leaving of the prototype works as intended:</p>
<pre><code>var B = function() { A.apply(this, arguments); };
</code></pre>

2,834,858 | 2,834,859 | Python Lambdas and Variable Bindings | <p>I've been working on a basic testing framework for an automated build. The piece of code below represents a simple test of communication between two machines using different programs. Before I actually do any tests, I want to completely define them - so this test below is not actually run until after all the tests have been declared. This piece of code is simply a declaration of a test.</p>
<pre><code>remoteTests = []
for client in clients:
t = Test(
name = 'Test ' + str(host) + ' => ' + str(client),
cmds = [
host.start(CMD1),
client.start(CMD2),
host.wait(5),
host.stop(CMD1),
client.stop(CMD2),
],
passIf = lambda : client.returncode(CMD2) == 0
)
remoteTests.append(t)
</code></pre>
<p>Anyhow, after the test is run, it runs the function defined by 'passIf'. Since I want to run this test for multiple clients, I'm iterating them and defining a test for each - no big deal. However, after running the test on the first client, the 'passIf' evaluates on the last one in the clients list, not the 'client' at the time of the lambda declaration.</p>
<p>My question, then: when does python bind variable references in lambdas? I figured if using a variable from outside the lambda was not legal, the interpretor would have no idea what I was talking about. Instead, it silently bound to the instance of the last 'client'.</p>
<p>Also, is there a way to force the resolution the way I intended it?</p>
