1,862,295 | 1,862,296 | Java: check for null or allow exception handling | <p>I'm wondering about the cost of using a try/exception to handle nulls compared to using an if statement to check for nulls first.</p>
<p>To provide more information. There's a > 50% chance of getting nulls, because in this app. it is common to have a null if no data has been entered... so to attempt a calculation using a null is commonplace. </p>
<p>This being said, would it improve performance if I use an if statement to check for null first before calculation and just not attempt the calculation in the first place, or is less expensive to just let the exception be thrown and handle it?</p>
<p>thanks for any suggestions :-)</p>
<p>Thanks for great thought provoking feedback! Here's a PSEUDOcode example to clarify the original question: </p>
<pre><code>BigDecimal value1 = null //assume value1 came from DB as null
BigDecimal divisor = new BigDecimal("2.0");
try{
if(value1 != null){ //does this enhance performance?... >50% chance that value1 WILL be null
value1.divide(divisor);
}
}
catch (Exception e){
//process, log etc. the exception
//do this EVERYTIME I get null... or use an if statement
//to capture other exceptions.
}

786 | 787 | Guard code after switch on enum is never reached | <p>I have just hit a confusing problem when trying to compile some code using g++ 4.4.3.</p>
<p>The code below compiles fine, but instead of hitting the expected assert when I pass an 'invalid' enum value, the function just returns 1. What I find even stranger is that when I uncomment the lines pertaining to the E3 enum value, things start working as expected.</p>
<p>The fact that there is no default entry in the switch block is by design. We compile with the -Wall option to get warnings of unhandled enum values.</p>
<pre><code>enum MyEnum
{
E1,
E2,
//E3
};
int doSomethingWithEnum(MyEnum myEnum)
{
switch (myEnum)
{
case E1: return 1;
case E2: return 2;
//case E3: return 3;
}
assert(!"Should never get here");
return -1;
}

{
// Should trigger assert, but actually returns 1

<p>I'm working on an app that uses some SharedPreferences. Everything in that aspect works fine, but after completely uninstalling and then installing again, I found that my SharedPreferences values were still being picked up. I ended up uninstalling and then pulling up an adb shell and found that indeed... under /dbdata/databases/mypackagename/shared_prefs/ there were still files there. I would assume that they should have been removed...</p>
<p>I'm using a Samsung Captivate running the Serendipity rom... Again, I can only imagine that that has something to do with it, but I'm not certain.</p>

<p>The differences I see are:</p>
<ul>
<li>the first is "closure-style", while the second is not.</li>
<li>the first defined a factory function (*) which creates an object and binds the result of this factory to <code>foo1</code>, the second instead is a plain singleton, and you cannot have more instances unless you do .prototype hacking.</li>
</ul>
<p>Are there any other differences ? <code>this</code> binding behavior ? unexpected browser detonations ? crying kittens ?</p>
<p>(*) In other words, I could do something like</p>
<pre><code>var fooFactory = function () {
return {
init: function () {
alert(this+" hello foo1");
}
};
}
var foo=fooFactory();
var bar=fooFactory();

<p>and <code>foo</code> and <code>bar</code> are now two different instances of the same "class" (actually, they are just two Objects that "happen" (by construction) to have the same interface).</p>

<pre><code>function displaySearchResults(resultsList) {
var length = resultsList.length;
var searchDiv = document.getElementById('search-results');
//CLEAR DIV
if(searchDiv.hasChildNodes()) {
for(var i=0; i<searchDiv.childNodes.length; i++) {

var element = resultsList[i];
var rowDiv = document.createElement('div');
rowDiv.id = 'search-results-row' + i;

rowDiv.setAttribute('onclick', 'mapCurrentContact(' + i + ');');
rowDiv.innerHTML = element.firstName + ' ' + element.lastName;
searchDiv.appendChild(rowDiv);
}
}
</code></pre>
<p>However it starts running the ADD CHILDREN portion of the function before the CLEAR DIV loop has a chance to finish. So for instance, if the function finds 4 childNodes in the div and begins looping through to remove each one with the id of search-results-row, it will only get through 2 or so before it begins appending the new set of results that was initially passed into the function.</p>
<p>I know that Javascript runs asynchronously, but I thought that functions themselves at least run top down so the bottom portion should not do anything until we reach that part of the code? I have tried all sorts of other alternatives such as running the CLEAR DIV portion in its own function and then calling the ADD CHILDREN portion at the end, but I always get the same results. What am I missing here!?!</p>

3,831,387 | 3,831,388 | How to hide an element, based on its text, with JavaScript? | <p>I'm a beginner developer. I'm trying to hide a div that is dynamically added to the page by a 3rd party JavaScript for aesthetic purposes.</p>
<p>The problem is that the div has no <code>id</code> attribute; is this even possible? Do divs have any inherent attributes based on the order in which they load? Or is there any way to search for a string of text and hide the element?</p>
<p>For example, removing <code><div>happy New year</div></code> based on its text <code>happy New year</code>.</p>

var actionHoverOutListener = function () {

};
// Add a hover listener for actions
$(".magic").hover(
actionHoverInListener, actionHoverOutListener
);
</code></pre>
<p>This works fine, but the issue is speed. If I hover over and out of the "magic" div too quickly, it never hides the popout. It's as if the hide call is ignored because the show is still animating the slide.</p>
<p>The hover out method is being called correctly: I have put in logging code to make sure it is getting called. So, the problem is that the hide does not cancel the show. Is there a way to do this?</p>
<p>Thanks!</p>

<p>For example:</p>
<p><code>3,47</code> or <code>3.45</code></p>
<p>How can I enforce the double should always contain a <code>.</code> precision character?</p>
<p>Problem is once I serialize the class containing this double to XML, it gets shipped to other systems expecting a standard result. </p>
<p>So after reading your responses (and thanks), do you guys recommend changing the property to a string, (making the replacements in a string), so that it serializes with the string value (not the double)?</p>

20,263 | 20,264 | jquery escape character issue? | <p>I have this jquery issue that seems to only break when using background image url. My impression is that it looks like a character escape issue, but i could be wrong.</p>
<p>Here's what i have for a working demo version: <a href="http://jsfiddle.net/W4CZG/" rel="nofollow">http://jsfiddle.net/W4CZG/</a></p>
<p>Essentially i have some draggable divs with inline style in the html:</p>
<pre><code><div class="dragme" style="background-color:#ccc;">1</div>
<div class="dragme" style="background-image:url(images/image1.gif);">2</div>
</code></pre>
<p>On the script, i've currently used the following to add a span tag inside the droppable area to set the style:</p>
<pre><code>$(this).html('<span style="' + draggable.attr('style') + '"></span>');
</code></pre>
<p>The first div, with the background color, works fine. Looking in firebug, it creates something like:</p>
<pre><code><span style="background-color: rgb(204, 204, 204);"></span>
</code></pre>
<p>If i use any other style - like margin, font, etc - it works also. But my problem, and hence my question here, is with the background image, the generated span tag doesn't get the background image inline style, it instead gets all messed up? In firebug i see this:</p>
<pre><code><span );="" image1.gif="" images="" style=""></span>
</code></pre>
<p>Is this a charcater escape issue? And more importantly, how do i fix this?</p>
<p>Thanks for your time!</p>

<p>I am trying to find a way to delete an internal resource after an app installs. More specifically, I have a zip file included in the apk, that I unzip to the SD Card when the app is first run.

<p>I access the zip file with,</p>
<pre><code>Resources resources = this.getResources();

</code></pre>
<p>But am uncertain how to then delete the resource (if even possible).</p>
<p>I know one may ask why not simply install the app to SD Card at download. But the app includes a screen widget, and installing apps to the SD Card and using a screen widget is problematic.</p>
