Hi kajastancos,

I run it for Windows, Fedora Linux and Sun Solaris operating systems without any modification and any problem. I checked it once more for you.

Thanks for your comment and interest.

your code is a bit buggy, please test on several different platforms, before posting, kthxbye

package net.cavdar.staticinitializer;

/**
* Says “Hello World!” without main method. A simple use of
* static initialisation.
*
* @author accavdar
*/
public class HelloWorldWithoutMain {
static {
System.out.println(”Hello World!”);
// you need the next line to avoid ClassNotFoundException
new HelloWorldWithoutMain();
System.exit(0); // prevents “main method not found” error
}
}

Yes, you can print this. But static initializer is useful for initializing resources/variables shared by all instances of a class.

Here, I use the traditional “Hello World” example to demonstrate the usage of “static initializer blocks”. More meaningful and detailed example can be found in the link below:

Thank you all for your nice comments.

Trick is nice but what are you trying to preach; can it ever be used in real life scenario.
