What is the output of the second println statement in the main method?

public class Foo $\{$

int $i$;

static int $s=0$;

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

Foo $f1=$ new $F()$;

System.out.println$("$f$1.$i is $"+$ f$1.$i $+"$ f$1.$s is $"+$ f$1.$s$)$;

Foo $f2=$ new $F()$;

System.out.println$("$f$2.$i is $"+$ f$2.$i $+"$ f$2.$s is $"+$ f$2.$s$)$;

Foo $f3=$ new $F()$;

System.out.println$("$f$3.$i is $"+$ f$3.$i $+"$ f$3.$s is $"+$ f$3.$s$)$;

$\}$

public Foo$()\{$

i$++$;
