QUESTION $3$

Analyze the following code.

public class

static int $n=2$;

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

xMethod$($n$)$;

System.out.println$("$n is $"+$ n$)$;

$\}$

static void xMethod$($int $n)\{$

n$++$;

$\}$

$\}$

A$.$ n should not be declared static.

B$.$ n can not be assigned as argument of XMethod

C$.$ The code prints $n$ is $1.$

D$.$ The code prints $n$ is $2.$

E$.$ The code prints $n$ is $3.$

QUESTION $4$

What is the printout of the second println statement in the main method? public class Foo $\{$

static int $i$;

static int s;

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

Foo f$1=$ new Foo$()$;

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

Foo f$2=$ new Foo$()$;

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

Foo f$3=$ new Foo$()$;

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

$\}$

public

i$++$;

s$++$;

$\}$

$\}$

A$.f2.i$ is $1f2.s$ is $1$

B$.f2.i$ is $1f2.s$ is $2$

C$.f2.i$ is $2f2.s$ is $2$

D$.f2.i$ is $2f2.s$ is $1$
