Loops and Random

What does the following method do $($assume the Random class has been imported$)$:

public static void question$5()\{$

int val$=1$;

int count $=0$;

boolean done $=$ false;

Random $r=$ new Random$()$;

while $(!$done$)\{$

int num $=r.$nextInt $(3)+2$;

if $($num $-1==$val $)\{$

count$++$;

val $=$ num;

$\}$ else $\{$

count $=0$;

val$=1$;

$\}$

done $=$ count $==3$;

$\}$

$\}$

sequence: $321$ occurs.
