The difference is there in the API documentation. `System.loadLibrary(String libname)` lets you load from the default path -- The Java library path.

The other `System.load(String filename)` lets you load it from an absolute path, which you must specify as your filename.

If you don&#39;t want to mess with you `java.library.path` environment variable, you should use `System.load()`

I have a `UIImageView` where I have set the frame size to `x = 0, y = 0, width = 404, height = 712`.
In my project, I need to change the image in `UIImageView` dynamically. 

I am using this code to change the image: 

    self.imageView.image = [UIImage imageNamed:@&quot;setting-image.png&quot;];

The problem is, when the `*.png` image size is smaller than the `UIImageView` frame size, the image stretches. I don&#39;t want it to stretch. Is there any way to do that? 

How to stop an image from stretching within a UIImageView?

In Python, I have a list:

    L = [1, 2, 45, 55, 5, 4, 4, 4, 4, 4, 4, 5456, 56, 6, 7, 67]  

I want to identify the item that occurred the highest number of times. I am able to solve it but I need the fastest way to do so. I know there is a nice Pythonic answer to this.  



Find the item with maximum occurrences in a list

What is the difference between [`System.load()`][1] and [`System.loadLibrary()`][2] in java?

I want to load a library but I don&#39;t want to add the path to environment variables. 
Will any one of these help?

JCombobox in Java 7 has been updated to use generics - I always thought it was a bit of an oversight that it didn&#39;t already so I was pleased to see this change.

However, when attempting to use JCombobox in this way, I realised that the methods I expected to use these generic types [still just return `Object.`][1]

Why on earth is this? It seems like a silly design decision to me. I realise the underlying [ListModel][2] has a generic `getElementAt()` method so I&#39;ll use that instead - but it&#39;s a bit of a roundabout way of doing something that appears like it could have been changed on JComboBox itself.

Why isn&#39;t getSelectedItem() on JComboBox generic?

I am a Java programmer who is new to the corporate world. Recently I&#39;ve developed an application using [Groovy][1] and Java. All through the code I wrote used quite a good number of statics. I was asked by the senior technical lot to cut down on the number of statics used. I&#39;ve googled about the same, and I find that many programmers are fairly against using static variables.

I find static variables more convenient to use. And I presume that they are efficient too (please correct me if I am wrong), because if I had to make 10,000 calls to a function within a class, I would be glad to make the method static and use a straightforward `Class.methodCall()` on it instead of cluttering the memory with 10,000 instances of the class, right?

Moreover statics reduce the inter-dependencies on the other parts of the code. They can act as perfect state holders. Adding to this I find that statics are widely implemented in some languages like [Smalltalk][2] and [Scala][3]. So why is this opposition to statics prevalent among programmers (especially in the world of Java)?

PS: please do correct me if my assumptions about statics are wrong.

Why are static variables considered evil?

Assuming that `arraylist` is defined as `ArrayList&lt;String&gt; arraylist`, is [`arraylist.removeAll(arraylist)`][1] equivalent to [`arraylist.clear()`][2]?

If so, can I assume that the `clear()` method is more efficient for emptying the array list?

Are there any caveats in using `arraylist.removeAll(arraylist)` instead of `arraylist.clear()`?

When running our Maven build, a member of my team gets a NoSuchMethodError in one of the dependant plug-ins when executing. However, when we run `java -version` from her command line, it indicates Java 1.6.0_26.  The error obviously seems to be screaming that Maven is using Java 5.

How do I figure out and change what version of Java is being used by Maven?

3 potentially important notes:

1.  This is executed at the command line, not using Eclipse plugin
2.  JAVA_HOME is set to a Java 1.6 JDK
3.  Using Maven 2.2.1

How do I figure out and change which version of Java Maven is using to execute?

How can `^\d+$` be improved to disallow `0`?

EDIT (Make it more concrete):  

**Examples to allow:**  
1  
30  
111  
**Examples to disallow:**  
0  
00  
-22

It doesn&#39;t matter if positive numbers with a leading zero are allowed or not (e.g. `022`).

This is for Java JDK Regex implementation.

What is the regex for &quot;Any positive integer, excluding 0&quot;

I have a listview which is fetching data from sqlite database by Json.
    
I want to turn it into dynamic listview that at the end of scroll, a &quot;load more items&quot; appears in the footer of the list while loading more items and adding them to the adapter (for example 10 items each time). I have problem in implementing this feature. Please help me with it. Thanks.

dynamic listview adding &quot;Load more items&quot; at the end of scroll

What exactly does `-rdynamic` (or `--export-dynamic` at the linker level) do and how does it relate to symbol visibility as defined by the `-fvisibility*` flags or visibility `pragma`s and `__attribute__`s?

For `--export-dynamic`, [ld(1)][1] mentions:

&gt; ...
&gt; If you use &quot;dlopen&quot; to load a dynamic object which needs to refer back
&gt; to the symbols defined by the program, rather than some other dynamic
&gt; object, then you will probably need
&gt;            to use this option when linking the program itself. ...

I&#39;m not sure I completely understand this. Could you please provide an example that doesn&#39;t work without `-rdynamic` but does with it?


**Edit**: 
I actually tried compiling a couple of dummy libraries (single file, multi-file, various -O levels, some inter-function calls, some hidden symbols, some visible), with and without `-rdynamic`, and so far I&#39;ve been getting **byte-identical** outputs (when keeping all other flags constant of course), which is quite puzzling.
