Override the main method

[nemo zou]

I got confused about the this question in Enthuware test 6. I thought the answer is "print nothing" because I remember it is fine to override the main methods. Why an error would be thrown here?

First of all, that's not an override! Only inherited instance methods can be overridden.

Secondly, you'll get an error because the JVM is looking for a method public static void main (String[]) - exactly. So because the return type is long, the JVM can't find the main method to run your application and you'll get something like:
Error: Main method must return a value of type void in class TestClass, please define the main method as:
public static void main(String[] args)

Hope it helps!
Kind regards,
