Printing message on Console without using main() method

Question

I was asked this question in an interview.

How to print message on console without using main() method?

Answer 1

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

    }
}

Because the static initializer block is executed when the class is first loaded, we can print out “Hello World” without writing a main method. The execution is stopped using “System.exit()” command. So, we prevent “main method not found” error. It's quite a tricky question
