Can't we run main method inside enum?

I had seen a video where, main() can be run with in an enum. I am trying to do the same but it's not working.

Here is my code

public enum EnumMain {                             
   ABC, XYZ;                                       
   public static void main(String[] args) {        
     System.out.print("MIAN");                     
   }                                               
}

Output (The code compiles fine)
Error: Could not find or load main class EnumMain

I think this has something to do with the Java version, may be in Java 8, they are not allowing to run main() method from enum

the main method is suppose to be placed inside a class an not enumerators...

public static void main(String[] args) {        
     System.out.print("MIAN");                     
   }
