Assuming that the user provides $99$ as input, what is printed by the following code snippet?

int a; $$ int b;

Scanner in $=$ new Scanner$($System$.$in$)$;

System.out.print$("$Please enter a number: $")$;

b $=$ in$.$nextInt$()$;

if $($b $>300)\{$

$$a $=$ b;

$\}$

else $\{$

$$a $=0$;

$\}$

a $=$ a $+2$;

System.out.println$("$a: $"+$ a$)$;
