Use the method f$()$ below to answer the next $2$ questions:

public static int f$($int$[]$ nums$)\{$

int result $=-99$;

for $($int i $=0$; i $<$ nums.length; i$++)\{$

if $($nums$[$i$]==0)\{$

result $=$ i;

$\}$

$\}$

return result;

$\}$

Using the method f$()$ defined above, what will be printed? If you believe the code contains an error, then write ERROR as your answer.

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

int$[]$ a $=\{15,0,2,7\}$;

System.out.println$($f$($a$))$;

$\}$

Using the method f$()$ defined above, what will be printed? If you believe the code contains an error, then write ERROR as your answer.

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

int$[]$ b $=$ new int$[50]$;

System.out.println$($f$($b$))$;

$\}$
