Answer / unknown
You can use Macros to do this job if the goal is not to use the name "main" in the function.
Example 1:
#define func main
void func()
{
printf("hello");
}
Example 2:
If the word main should not be displayed then,
#define func m##a##i##n
void func(){
printf("hello");
}
If you really want not to use main function at all, then you have to override the main function call manually. The call to the main function is made by another function called "_start()". The function is called by the compiler and then the main function is called by that.
#include<stdio.h>
#include<stdlib.h>
void _start(){
puts("Hello World
");
exit(0);
}
Here, you have to compile the program with gcc -nostartfiles, so that the startfile(ie main) is being overridden with your code.

Sorry. Missing return statement in the former post
public class classWithoutMain {
private static int x = load();
private static int load() {
System.err.println("This message will be printed");
System.exit(0);
return 0;
}
}
