You are told that class C is a subclass of AC$.$ Therefore, how many of these $14$ numerated statements are valid?

public interface I$\{$

int i $=8$;

public int getVal$()$;

$\}$

public abstract class AC implements I $\{$

public abstract int getNum$()$;

$\}$

public class MyProg extends AC$\{$

public static void main$($String$[]$ args$)\{$

System.out.println$($I$.$i$)$;

I.i $=10$;

I i$1=$ new AC$()$;

I i$2=$ new C$()$;

System.out.println$($i$2.$getVal$())$;

System.out.println$($i$2.$getNum$())$;

C c$1=$ new I$()$;

C c$2=$ new AC$()$;

System.out.println$($c$2.$getVal$())$;

AC ac$1=$ new AC$()$;

AC ac$2=$ new C$()$;

System.out.println$($AC$.$i$)$;

System.out.println$($ac$2.$getNum$())$;

System.out.println$($ac$2.$getVal$())$;

$\}$
