public static void main(String arg[ ] ) in java is it fixed?

Question

I was recently asked in an exam if public static void main(String arg[]) format of main method was fixed? Can we change it? Can we use main

Answer 1

The main method must be public so it can be found by the JVM when the class is loaded. Similarly, it must be static so that it can be called after loading the class, without having to create an instance of it. All methods must have a return type, which in this case is void.
