Q$1($I believe java was used$)$

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

int$[]$ array $=$ new int$[5]$;

for $($int a : array$)\{$

System.out.print$($a $+"")$;

$\}$

System.out.println$()$;

$\}$

What is the output?

A$)00000$

B$)12345$

C$)$ No output because the array is not initialized

Q$2$

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

int$[][]$ myNumbers $=\{\{1,2,3,4\},\{5,6,7\}\}$;

System.out.printf$("\%$d $\%$d $\%$d

$",$ myNumbers.length, myNumbers$[0].$length, myNumbers$[1].$length$)$; $\}$

What is the output?

A$)244$

B$)234$

C$)243$

Q$3$

public class Recursion $\{$

public static void permutation$($int num$)\{$

if $($num $==0)$ return;

System.out.print$($num $--+"")$;

permutation$($num$)$;

$\}$

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

permutation$(5)$;

$\}$

$\}$

What is the output?

A$)43210$

B$)543210$

C$)54321$

D$)$ There is a bug and the program will never stop
