IS IT POSSIBLE TO EXTEND THE CLASS WHICH HAS MAIN FUNCTION???

Yes, it is possible to extend the class which has main function. When i tried it using notepad and command prompt, i got the expected output. In NetBeans, i got a message...

The file has more main classes.

and it asked me to chose the main class from the list. When i choose the super class which has main(), i got the correct output. Also the output is correct when i choose the subclass. But i think it is stupidous to extend a class having main(). I didn't find any answer in Google for this question and i think this kind of inheritance has no real application. The program which i tried is...

public class psvm_class 
{
    int a=5;
   
     public static void main(String args[])
    {
        System.out.println("hai in main()");                                          
        demo obj=new demo();                                   
        obj.display();                               
    }
}
class demo extends psvm_class
{
    void display()
    {
        System.out.println("hai in demo class");
        System.out.println("value of a is "+a);
    }
}

OUTPUT:

hai in main()
hai in demo class
value of a is 5

The above program has two main() functions in it, one which is in psvm_class. Since class demo inherits from psvm_class, it also has one copy of main() !!!!! But still the program runs without any error!!!!!
