Assuming line $3$ generates a random number between $[1-500],$ which one of the following is true about the following code:

$1.$ ArrayList lst $=$ new ArrayList$()$;

$2.$ for $($int i $=0$; i $<400$; $++$i$)\{$

$3.$ int rnd $=1+($int$)($Math$.$random$()*500)$;

$4.$ if $(!$lst$.$contains$($rnd$))\{$

$5.$ lst$.$add$($rnd$)$;

$6.\}$

$7.\}$

It only adds values to the list that are not already in the list

Compile error because contains method returns an int value

It only adds duplicate values to the list
