Running Java program without main method

Question

I know we can write programs without main method. I tried this but I am not getting an output.

public class Hello
{
    static{
        System.out.println("Hello World");
        System.exit(0);
    }
}

Can someone help me with this?

Answer 1

This would have worked fine till Java 6. It will compile correctly even now but wont show the Output and throw error saying Main method missing.

In Java 6 by placing the System.exit(0); just after print statement would have served the purpose and before finding the main method it would have executed and showed the result but this no more happens from Java 7 and above.
