For loop

I was doing some search on for loops and i bumped on this tiny code which is confusing to understand. below is the code



class Ex

{


public static void main(String[] args)

{

int i;

for(i=0, System.out.println(i); ; i++)

{

}

}

}

Now the above code runs fine. But when i declare the entire variable in inside the for loop like "for(int i=0, System.out.println(i); ; i++)" it throws error " ; expected" .

Now can any kindly explain me the difference?

Thank you

Read paragraph 14.14.1. in the JLS: the for-initialization part can either be a local variable list declaration or a list of expression statements; they can't be combined.
