Google Syntax Highligher for WordPress colorizes your code on-the-fly. It supports most programming/scripting languages such as C++, PHP, Perl, Ruby, and much more. The syntax is simple — just put your code inside <pre> tags and assign them the attributes name="code" and class="thelanguage".
<pre name="code" class="java">
public static void main(string[] args){
System.out.println("Hello World Again!");
}
</pre>
public static void main(string[] args){
System.out.println("Hello World Again!");
}
You can learn more more ways to customize your highlighted code in the Google code wiki entry on Usage - syntaxhighlighter. Also check out the full list of supported languages on Google Code.
The Singleton Pattern is quite simply a design pattern that allows only one instance of itself to be created per application pool or application instance and provides one point of access to the single unique instance.
Ensure a class only has one instance, and provide a global point of access to it.
public class Singleton {
protected Singleton() { }
private static Singleton _instance = null;
/**
* @return The unique instance to this class.
*/
public static Singleton getInstance() {
if(null == _instance) {
_instance = new Singleton();
}
return _instance;
}
}
As you can see the idea is not to use public constructor. With protected or private constructor in some other class we can not do something like this:
Singleton objSingleton = new Singleton();
The other idea is to use static method getInstance();
this is how it works in some test client:
public class TestSingleton() {
public static void main(string[] args) {
Singleton objSingleton;
objSingleton.getInstance();
}
}
WebProgBlog is a blog about several areas of my interests. The one side is programming, web, web design, web programming, OOP and my experience in the web world. The other things I am going to write about are things I like to do when I have time: drawing and playing tennis.
