JAVA Step $1.$ Add a private helper method:

$//$ return a partially filled int array with all elements from the

$//$ ArrayList param in the same sequence and $5$ extra spots at the end

private static int$[]$ toIntArray$($ArrayList list$)\{$

$//$ ADD code

$\}$

We want to copy the data from the ArrayList to an array. To allow space for additional operations, we also want this array to be a partially filled array. We accomplish this by creating an array whose capacity is $5+$ list.size$().$
