       System.out.println ("hello2"); 
    } 
} 
class main  { 
   public final static void main (String [] args)  { 
       System.out.println ("hello"); 
    } 
} 



Correct Option is  : D

Note

Observe that the given code does not follow the standard Java naming convention.

The class names should start with a capital letter.

There are questions in the exam that contain similar non-conventional and confusing names and that is why we have kept a few questions like that in this question bank.
