What is copiedNums' length after the code segment?

int$[]$ originalNums $=\{1,2,3,4\}$;

int$[]$ copiedNums $=\{0,0,0\}$;

copiedNums $=$ copy$($originalNums$,2)$;

public static int$[]$ copy$($int$[]$ nums, int changeAmt$)\{$

$$ int$[]$ modifiedNums $=$ new int$[$nums$.$length $*$ changeAmt$]$;

$$ int index;

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

$$ modifiedNums$[$index$]=$ nums$[$index$]$;

$\}$

$$ return modifiedNums;

$\}$
